[非廣告] 犯罪/心理/驚悚/懸疑小說推介

熟悉我的人都知道其實我就算看書,都是比較喜歡看犯罪/心理/懸疑小說類的書,當中涉獵翻譯文學或是本土的都看。最近有些朋友跟我聊聊後問我有沒有類似的書可以推薦一下,我就心血來潮,簡單的整理了過去幾年我看下來特別喜歡的幾本。(幸好平常讀完如果比較喜歡的話都會放上Facebook,這次只是要再Shortlist而已,哈!)。這次整理的只有中文,下次輪到英文的吧!

[新聞專題]:尿液墨水

新聞:【尿液做隱形墨水】納粹女囚寫下秘密筆記 紀錄殘酷醫療實驗

二戰期間利用活體做科學/醫學實驗都不是第一次聽到的事。納粹德軍在柏林外的文斯布呂克(Ravensbrueck)曾關押過共13萬人,當中部分波蘭女囚以自己的尿液當「隱形墨水」在家書字裡行間偷偷寫下筆記,向外界透露營內的恐怖及殘酷實驗實況。

這些家書主要是記錄1943年到1944年間進行的死亡實驗。女囚以薄木棍做筆,以尿液為墨,寫在家書空白的部分(實行真正的「read/write between the lines」)。尿液因為當中的酸性在信紙上很快產生化學反應而褪色,繼而「隱形」。讀信人必須要加熱信件,才可讀到收起來的內容。

這令我聯想起另外一個我之前接觸到尿液的另一個特別用途:紋身墨水!

聖誕老人的骨骸及真實樣貌?

意大利巴里 (Bari) 鎮上的一個教堂地下墓室已經滲水接近一千年,滲水的地方影響了牆壁跟墓室裡的骨骸。 1953 年 5 月 5 日,該教堂的一名教職人員因此要打開一個 866 年都沒有打開過的棺木。

這副棺木裝著的是聖尼古拉斯 (St. Nicholas) 。 St Nicholas 在荷蘭語被稱為 Sinterklaas ,後來我們現代轉化名字為 Santa Claus 。

打開 St Nicholas 棺木後看到的是骨骸亂七八糟的放著。除了頭顱是正正的安放於中間,其他的骨頭包括長骨 (Long Bones) 等都可以找到,但有部分已成碎片。據了解,當打開後發現棺裡有四分之三的骨骸都是濕的。故此,骨頭的狀況非常不良──易碎變成碎片。只有比較明顯有特別照顧頭顱。頭骨都差不多全個保存下來。骨骸其後都拿去做記錄。

直到 1957 年復修好後,當時的研究員,也是一名解剖學的教授 Luigi Martino 做了現代西方認知以來的首位教授去做一個骨骸研究。

按照骨骸研究,得出來的結果是跟我們一般的「聖誕老人」的認知畫面不太一樣。

我們認知的是這樣:

身材圓滾滾的他臉上長雪白的長鬍子,身穿紅衣、戴著紅帽,總是掛著和藹可親的笑容,會背著裝著禮物的大包,黑夜中騎著麋鹿拉的雪橇到達每個乖孩子的家,期待著他會在煙囪裡爬進來及丟禮物到襪子裡!

而真實呢?

按照 X 光跟骨骸的研究及量度,骨骸是屬於一名男子,年齡超過 70 歲,約於 72 到 80 歲區間(歷史上說聖尼古拉斯死時 75 歲)。他的身高屬於當時的平均身高,約五呎四寸左右 (163cm) ,瘦到中等身材。

聖尼古拉斯的臉比較短及闊,額頭及顴骨也寬,下巴微微凸出。他中等寬度的鼻子有明顯的已經愈合生前創傷, 跟記載中提及與另一位主教因爭執而打架被打斷鼻樑吻合。牙齒方面,因年事已高而有蛀牙及有於盆骨位及脊椎骨有嚴重的關節炎。

按照這些骨骸給我們的資訊,當中很多不同的學者及專家都嘗試給聖誕老人配上臉孔 (Facial Reconstruction) 。而最近期的一個由於塑顏領域的權威 Dr Caroline Wikinson 於 2014 年參考土耳其男性的組織深度加上 CGI 技術,塑造的聖誕老人樣貌 (我覺得他這個樣子好和藹可親啊!):

為甚麼是土耳其?因為聖尼古拉斯是在小亞細亞(現今土耳其境內)出生的,後來更當上了主教。在當時小亞細亞的主教都是穿棕色或咖啡色袍,而他的五官應該是比較地中海感覺,皮膚也偏向小麥色。咦?不就跟我們認知的都不一樣嗎?

公元 343 年,他的遺體葬在土耳其,後來更變成一個朝聖地。在 1087 年春天,一群駐意大利巴里鎮的基督教水手擔心由於土耳其脫離了羅馬帝國統治,聖尼古拉斯的遺體會遭遇不測,他們就越洋過海到巴里取了大部份骨骸回義大利。

另外有趣的是,聖尼古拉斯的骨骸都浸在散發玫瑰香味的液體裡。每年的十二月六日都是聖尼古拉斯日(有些國家會選擇慶祝這天代替十二月二十五日聖誕節),都會有專人於這天收集這玫瑰香味的液體,但到現在為止都不清楚液體的來源。

我們現在知道,聖誕老人不是穿紅衣,沒有圓滾滾的身材,也不是白皮膚的。不過,這個從小就被灌輸的這個講法,原來來自於美國詩人克里門.莫爾 1822 年的一首詩 “A Visit from St. Nicholas” ,到後來就被編成我們熟悉的 “A Night Before Christmas” 。而到底,我們今天講聖誕老人的一些特色都跟聖尼古拉斯有關嗎?下面就探討幾個吧!

「…會背著裝著禮物的大包…」

聖尼古拉斯以他慷慨的善舉著名,他都不吝惜,能幫的,能給的都願意取做。此舉就承傳成聖誕老人的特徵:帶著大包的禮物送禮。

「…到達每個乖孩子的家…」

關鍵是:孩子!相傳在森林裡有一個惡魔有一天看到三個迷路小孩,他就把他們殺了肢解後,放到木桶醃製。三個月後,聖尼古拉斯突然出現把他們復活了!聖誕老人愛護小孩子的說法就流傳下來了。

「…期待著他丟禮物到襪子裡?」

聖誕老人的父母很早就過世,留下很多財產給他。相傳他得知有有一戶人家的三個女孩都長得善良美麗,但因為沒有嫁妝所以遲遲不出嫁。她們亦因為家境貧困,所以要從事性工作以賺取生計。有一天,聖尼古拉斯就把帶同他有的金幣從窗口丟了一袋進去,剛好落在她們在晾得襪子裡。之後就演變成聖誕節要掛襪子,亦有些傳統會放錢幣巧克力,以代表以前把金幣送給女孩們的慷概行為。

那如果要看真﹒Ÿ聖誕老人,代表我們要到芬蘭嗎?還是之前提及的意大利?

兩個都不是!天主教教堂他們會把聖髑(聖人的骨骸)以送贈形式送給其他教堂,而我們的聖誕老人,即聖尼古拉斯的骨骸都分別可以在以下國家找到:

  • 巴里,意大利(主要的遺骸都在這裡的地下墓室)
  • 奧地利
  • 白俄羅斯
  • 比利時
  • 保加利亞
  • 加拿大(多倫多、魁北克省、奧塔瓦)
  • 丹麥
  • 法國
  • 希臘
  • 德國
  • 意大利
  • 荷蘭
  • 羅馬尼亞
  • 俄羅斯
  • 蘇格蘭
  • 西班牙
  • 瑞士
  • 烏克蘭
  • 美國(紐約、加州等)

所以說 “Santa Claus is coming to town” 不完全對,應該是 “Santa Claus is in town” 。

我一直都不反對跟小孩子說有聖誕老人的存在,純粹覺得小孩子每年值得擁有特別期待一個節日的權利。現在,看來有更好的理由跟小朋友說有聖誕老人,只是跟我們平常看到的不太一樣。或者,這也可以是教授他們文化差異的好教材。

「這個世界原來曾經真的有聖誕老人啊!」此消息算是此亂世中的一絲安慰,一絲喜悅吧!

最後,祝各位聖誕節快樂!

“The Body in the Concrete”- Concrete Casket 101.

So last time, I expressed my concern on how the Hong Kong Police and Firemen had mistreated the crucial trace evidence, namely the concrete casket. And I also opposed their methodology. Some of the readers thought that police should be more experienced on handling these cases than me, and also thought that the law enforcement units had made this judgment after chains of thorough thinking.

I supposed I am not in a good position to comment further on how their approach was when they were at the scene. After all, I was not at the crime scene in person. Also, readers state that that was indeed the raw differences between theories, archaeology and the reality. I am only wishing to use the following space to replied to three of the main questions raised by the readers. I have also cited the Los Angeles Medical Examiners case report, in hope of the M.E. would be able to shed some lights on the questions the readers made from their study and research.

Question 1: The size of the concrete casket is too huge! May be they are not scanned because the law enforcement was not able to transfer them for scanning?

If you ever watched any crime shows on TV (of course, Bones is a good example. Everyone will yell “back to the lab!”), you will see they are always able to transfer whichever evidence they found back to the lab before further analyzing. Reality, not so much. This is how Ground Penetrating Radar comes into play. In archaeology, Ground Penetrating Radar (GPR) is used to detect and reflect any buried artifacts, monuments, archaeological sites. It is especially handy when archaeologists are about to look for hidden burial sites and buried remains. GPR allows noninvasive examination, and very helpful for experts and scientists to learn about the structure of the hidden architectures and bodies. Furthermore, size of a GPR is only about the size of a vacuum. Some companies even invented the GSSI Mini, which is about the size of a laptop for carrying scientists to have easy access in the field. All GPR and GSSI Mini come with a monitor, and very easy to connect to the laptop. That said, it is easy to document digitally the detected images. One may use slightly more time on using the GPR before stepping or unfold the crime scene, yet save the team and resources from doing extra and additional steps and procedures in the later investigation. In this case, that would be the suspicious broken palm, posture of the body, etc.

Question 2: It was mandatory to crack the concrete casket open, as the body was decomposing already.

News and police report claimed that the concrete casket was dried by the time of discovery. Yet, concrete would not dry but only cure and hardened. The hardening and curing of concrete, in other words, does not come from the evaporation of water from the chemical composition of the concrete. Rather the water molecules have transformed, merged and bonded together with the concrete particles as part of their chemical structure. An experiment pointed out that the mass of concrete before hardening/ curing is about the same with after [1]. The only slight difference between the mass was from the evaporation of the water on the concrete surface that with no cover. Last time, I have also mentioned that concrete is relatively porous. When cement hardens, it means that the water molecules and air molecules have filled in all those pores. This type filling makes concrete looks strong but indeed not. That said, it is relatively soft inside, while the outside of the concrete looks hard.

And for the body that was covered by the concrete, the decomposition of it liquefies from inside to outside, and all the decomposition was triggered by the enzymes in muscles. During the hardening process of the concrete, since it is a exothermic reaction (i.e. it releases heat in the whole process), the interior of the concrete casket would reach 175F in the first few days, which results an acceleration in the decomposition rate. After curing, the concrete becomes a good insulator that blocked the air and heat to reach the body, and thus successfully decrease the rate of decomposition again.

During the stage of decomposition, body liquids (any liquid in the body, you name it :)) would leak out of the body. Normally, as in general when a body is exposed to air, atmospheric air would help evaporate liquids and water. However, when a body like the one in this case is being buried in a concrete casket, all the fluid is trapped in the casket, and at the end turned the soft tissues into a mush. At the end, fluids would leak outside the casket, or concrete casket. This is not only something visual but also would give a strong odor. Evenly so, it does not mean an invasive act should be taken to the casket. Keep in mind that bodies starts breaking down the moment the heart stopped beating.

Question 3: Readers think that using merely textbook archaeology, i.e. using brush in the act, has not thoroughly considered the scenario at scene.

To be honest, this is some attitude that forensic scientists should have and maintain all along. In the forensic field, a lot of the tools we use are indeed very creative. For instance, you would find ladles on the autopsy table to scoop out fluid (for example inflammatory fluids in lungs) during autopsy; also would find those big stock pots in decomp bodies autopsy room for forensic anthropologists to do maceration. All these kitchenware is used with one and foremost premise: will not affect the quality of the collected evidences, or would not contemning evidences.

Los Angeles Medical Examiner Office claimed that there were only 5 cases of concrete casket located, till 2008, in the past 18 years in a report. They also stated in the report that, though cement and concrete affected the calculation or estimation of accurate postmortem interval, at the sam time they welly preserved all trace evidences [2]. In these 5 recorded cases, medical examiners were taken things slow, and excavate the bodies layer by layer in order to estimate the cause of death and time of death. Among all, LA medical examiners also indicated the frequent application of metal detectors and radiography in order to pinpoint the posture of bodes, and location. Sledgehammer and chisel are only implemented in a very much later stage, or only when they are sure it would not damage the body.

Back to the discussion, should we use heavy tools like sledgehammer and chisel, or only brush? Both. The foremost premise here is to not damaging the evidence. Only use heavy tools when the remains inside are well-documented. Also, the methodology with chisel should be go horizontally instead of vertically in order to reveal the context of the casket and the body.

Sad but true, concrete casket or related research is not commonly seen and discussed in the academia. These caskets can only open when all the conditions and situations are well-documented. In delicate crime scene like this one, officials should prioritize the preservation of crime scene in front of investigation just yet.

“The Body in the Concrete”- Dig or Not Dig, This Is the Question.

On March 30, 2016, Hong Kong local media, Apple Daily reported about a homicide that with a concrete-made casket. The concrete was found in one apartment in one of the neighborhood in Hong Kong, Tsuen Wan. The concrete casket was 1m x 1m x 0.5m and covered with a wooden box, and was placed in the center of the living room. Other than the concrete-wood casket, there were a lot of air-fresheners placed in the living room too. Police and firemen arrived the scene, and found the strong odor is originated from the wooden box in the living room. They decided to crack the casket, and handled the body to the M.E. right out of the casket. From the angle of forensic anthropology, and forensic archaeology, I would like to point out that the methodology police and firemen used to handle the casket is not appropriate.

Recap: Forensic anthropology is the combination of osteology and physical anthropology that applied in the legal context. Usually, forensic anthroplogists would only deal with human remains in advanced decomposition, skeletonization, human bone fragments, burnt remains, or other remains that have difficult time to give a positive identification from soft tissues.

Back to the case, first and foremost, the concrete casket. Concrete is the cured cement. Cement is a relatively alkaline material and very porous in itself. Concrete casket is very effective in insulating the body from contacting the air, which in turn, slows down the reproductive rate of bacteria within the body, as well as decreases the probability for flies laying eggs on the body. For, soft tissues decomposition mostly because the bacteria within digested our body and the occurrences of maggots. These two teeny tiny organisms enjoy the decomposition feast the most! Also, because the concrete could insulate the contact between the air and the body, the decomposition rate in general is slower in the concrete casket than exposing it in the air. That said, if the correct evidence collection methodologies used, a lot of physical, biological and trace evidences would be too preserved in the concrete casket. Therefore, without examine the concrete casket and use chisel or sledgehammer to break the concrete would be one serious wrong move, and here are the three main reasons:

1. Cracking the concrete casket is an invasive act. Once the concrete is cracked and broken, no one could recover it back to the original context. A fluoroscopic examination should be done and evaluated before any invasive act. With today’s technology, it would be easy and efficient to scan the whole concrete block before cracking it open. That way would allow the M.E. and corresponding law enforcement agents have a better understanding with the posture, number of bodies, and position of remains. Also, some of the remains might liquidfy or oxidize once contacted with air because of some chemicals they exposed to before concealed in the concrete. Straightly cracking it open, simply ignored this possibility.

2. Another risk of cracking open the concrete casket directly would be: what if there are more than one body? Although according to the intel and the missing person report, there was only one missing individual, and also because of this, police mainly focuses on looking for this particular person. Yet, if there are really more than one set of remains, directly using a chisel or sledgehammer without scanning the concrete in advance, would possibly damage the remains inside. The concrete casket, like the apartment, is a crime scene. One of the main missions for forensic anthropologist to determine first and foremost, would be the minimum number of individuals, or MNI. Anything in and out of the concrete casket is part of the evidences. Local news report stated that the right hand is cracked and broken because of the cement. Little did we know, if it was broken because of the cracking of casket, and thus resulted this postmortem trauma.

3. Direct usage of sledgehammer and chisel is not recommended. In forensic archaeology, the most useful tools would be those of carpenters–brushes, or even tooth brush. Only after fully documented the conditions of the casket would consider to crack the concrete. And would not use any chisel when getting close to the remains. That way, we could make sure the context of the body is well-preserved and complete-documented. Though this way is slow (could not deny this), yet can protect the remains and preserve the maximum amount of evidences, from pollen to hair to adipocere (aka grave wax).

Though body disposal in concrete is not a common case, it is definitely not the first. When handling body disposal like the abovementioned case, it is very important to keep in mind that speed of cracking the case is the least concern, as you have this fragile and one-time crime scene needed to handle and evaluate in optimum condition.

Forensic Daily #12: On Hair

Q: how useful it is if we found a hair from a crime scene? Will it tie us to a unsup?
A: yes, even put the unsup to jail! In general, each person loses 100 human hair everyday. It is easy to leave trace at the crime scene, or through physical contact. And each strand of hair is like a database that stores with data that allows scientists or experts to trace back up to 6 months ago. With each hair has a constant growing rate (in general) of 1 inch each month, it would help unlock data like medical condition, as well as the use of drugs too! A lot can pull out from the head of a hair, such as but not limited to: dietary habits, nutrition info, drugs consumption, diseases. With these specific info, linking a person to a crime scene is not as hard.

Forensics Daily #11: Forensic Countermeasures

Q: what is the definition of forensic countermeasures? This phrase sounds fancy!

A: this phrase in fact is pretty self-explanatory. First, you have to understand what “countermeasure” means. “Countermeasure” means an action, an incident, or a process that prevent the normal forensic protocols. It threatens the integrity of the forensic works.

Take an outdoor crime scene as an example. The forensic countermeasure could be the unpredictable rain (though it is a natural one), which would watch away unprotected evidence. It also could be scavenging animals, trespassed people, and so forth. As long as the acts that threatens the validity of forensic evidences that are not yet protected by the chain of evidences, regardless if it is natural or artificial, it is already a sort of forensic countermeasures.

Simple concept but with fancy saying, isn’t it?

Forensics Daily #10: Estimating the Time of Death from Drowning and Remains Found in Water

Q: Is it possible to tell if victims died from drowning and the time of death of remains found in water?
A: yes, for sure there are several ways to tell if the victims were drowned. One of the ways, that is also help determine the time of death of remains found in water is to evaluate the diatom level.
Diatom refers to a diverse group of algae. It has no specific structure or characteristics as it is consider a general term of groups of algae that inhabit the remains. Yet, the migration of diatoms, meaning the sequences of diatoms in the body should tell the time of the body in the water by calculating the schedule.
The same applies to the drowning victim too! Yet, during the drowning process, victim should also have inhaled some of the fresh water (only in fresh water will find diatoms!). So in the lungs, ME should be able to find fresh water and diatoms for calculation, as well as backward calculating the appearance of diatoms in order to work out the time of death.
P.s. Diatoms belongs to the Forensic limnology department, which is a sub-discipline of forensic botany, fyi : ) !

Forensics Daily #9: Dead Wives Tales

Q: are the dead wives tales true at all? Meaning, our nails and hair do grow after we died ?

A: Yes and No. Yes, because it does look like it grows, like illusion. No, because it is NOT REALLY GROWING.. Both hair and nails look like they grow after the heart stopped working because of the skin surrounding them are dehydrated. They shrink, and thus make it appear to be longer. Funeral homes sometimes will moisturize the bodies when they are doing the prep to counteract this.

Other than the hair and nails, the chin also dries out, and pulling towards the back of a skull, thus looks like more prominent. So does the goosebump effect, because of the contraction around the hair muscle (remember we talked about in the last few q&a, after we died, our muscles are not able to relax, not unable to contract!).

These all biological responses give the sense of horror!
