I picked up Neil Bradbury’s A Taste For Poison due to my interest in crime; while murder is never good, murder by poison seems particularly cold. The book’s emphasis is the history of poisons, their delivery, how they work on the body, and the tell-tale signs they leave behind. Chapters covers each of these poisons: insulin, atropine, strychnine, Aconite, Ricin, Digoxin, Cyanide, Potassium, Polonium, Arsenic and Chlorine, and chapters include poison cases and detail the sometimes limited technology available at the time. The author points out that murder by poisoning can’t be “spur-of-the-moment,” and it
“requires planning and a knowledge of the victim’s habits. It requires consideration of how the poison will be administered. Some poisons can kill within minutes; others can be given slowly over time, gradually accumulating in the body but still leading inexorably to the victim’s death.”
The intro explains that the book is “not a catalog of poisoners and their victims, but rather explores the nature of poisons and how they affect the body at the molecular, cellular and physiological levels.” This results in a unique book which is a mixture of chemistry, history and crime. The author explains that poison can be “delivered” through 4 “routes”: ingestion, respiration, absorption or injection. I’d never quite heard the subject of poison broken down with this specific simplicity, and I immediately began thinking of various poisonings and how they slot into the 4 methods of delivery
One of the points made in the book is these chemicals can be “both toxic and tonic” with a quote from the 16th century alchemist/physician Theophrastus von Hohenheim (Paracelsus): “It is the dose that makes the poison.” Enter insulin. A short, concise history of insulin takes us to the murder of Elizabeth Barlow, whose hubbie, Kenneth, sobbed over a photo of his wife as the police arrived to pull his dead wife from her bathtub. Then there’s a description of what insulin does to the body, and while insulin really is a miracle drug, in Elizabeth Barlow’s case (she was NOT a diabetic), a huge injection of insulin left some tell-tale signs which became clues that her death was an act of murder. In 1957, there was no “reliable test for insulin in the body.” In this landmark case, “1200 mice, ninety rats and several guinea pigs were used to determine that a lethal amount of insulin was in Elizabeth’s body.” Kenneth Barlow, a nurse, is “credited” for being the first person to commit murder using insulin. Another fascinating fact, most of the documented murders by insulin have been “committed by doctors, nurses, and other health care professionals.” Makes sense.
One of the frequently recurring themes in this book is the idea that physicians and scientists believe their training and expertise provide unparalleled insights that allow them to commit undetectable murders where others had failed.
Shocking facts here–animals killed in courtrooms as demo opportunities (probably plus a great shock factor to the jury), increasing patient deaths that defied all statistical possibility while murderous nurses ran rampant, and insulin-induced coma therapy as a cure for schizophrenia. (Note to doctors: AMAZING: comas will ‘cure’ all deviant behaviour.) Poisoning is a deadly serious subject yet the author delivers this detailed book with an irony that fits its content. Here’s an example:
Doctors giddily competed to see how many times a week they could put their patients into an insulin-induced coma, while others pushed the envelope to see how long their patients could be kept in a coma before reviving them.
It’s curious how many poisons have/had other uses–again that ‘dose’ quote. Arsenic for the face, castor oil for sickly children (thanks, mum!), Foxglove for the garden, the colour Prussian Blue….
In 1994, Safeway customers in Edinburgh were victims of a campaign poisoner who tainted bottles of water with Atropine. While the victims appeared to be random, they were collateral damage as part of a macabre plan for biochemist, university lecturer Paul Agutter to rid himself of his wife. Again, there’s a history of atropine, its uses and the tell-tell signs in the body.
Strychnine (“listed third in the top ten poisons by number of criminal cases, behind only arsenic and cyanide“) was a handy-dandy “pick-me-up” tonic for years but expanded into use as a “vermin killer.” A description of the crimes of the Lambeth Poisoner details the delivery, results and signs of this horrific poison.
Historically, Aconite plants appeared in herbal medicines for a variety of ailments and were used by dentists, but as the author notes, the margin of error between “numbing a pain and killing the patient were narrow.” (Let’s hope they were good at Math.) Enter Dr. Lamson who in the 19th century “went on a killing spree right out of a Christie mystery as he worked his way through his inlaws/family to get his hands on their inheritance.” In this case, a Dr. Stevenson, an expert in alkaloid poisons was called in to help the police. Stevenson’s “hobby” (well we all have to have hobbies, right?) was his ability to taste alkaloid “against a background of various bodily fluids.” Yes you guessed it.
Out of interest I looked on Amazon and found innumerable aconite herbal remedy products. Yikes!
Also included here is mention of Laboratory Number 1 in Moscow–a lab whose “trademark” “was to take existing poisons [and] using them in a way that was difficult to detect or trace back to Russia.” Cyanide mists, contaminated coffee (radioactive), poison tipped bullets. Also the poisoned umbrella tip “created” for the Bulgarian Secret Service used to kill Georgi Markov. All very James Bond–except that this is real– as was the murder of Alexander Litvinenko (polonium poisoning, Chapter 9). It’s difficult for me to narrow down the most shocking info here, but the most shocking mental image award goes to the section which details “death by bleach”–how one nurse injected bleach into dialysis ports eventually doing it in front of patients on dialysis machines!

Jolly subject for a book. Hope it didn’t give you any ideas.
Only to watch the nurses!
Whu you lookin’ at?
