This is an odd, idiosyncratic, fascinating, uneven, irritating, and important book: there's nothing out there like it. "Suicide and Attempted Suicide" is primarily a study of suicide methods---how people try to kill themselves (or, more often, try to get attention or help). It reads as if it were written by more than one author, or over an extended period of time: the tone bounces unpredictably from didactic to ironic to funny (be sure to read the chapter endnotes!).
The first half of the book touches on a wide range of suicide topics: history of suicide, the legal situation, treatment options, terminal illness, philosophical issues, euthanasia and assisted suicide. The information is interesting and well enough presented, but tries to cover too much ground in too few pages. A reader unfamiliar with this material will find it a reasonable, though patchy, introduction that can be followed up from the author's well-chosen "suggested reading" list.
The heart of the book is the second half, where it discusses suicide methods and their consequences in clinical detail. This treatment will surely be controversial, since the author provides "how to" (and "how not to") information that can be used either to commit suicide or to carry out a suicidal gesture.
I've seen only one other book that takes a similar approach, Derek Humphry's "Final Exit" to which this book will inevitably be compared. "Suicide and Attempted Suicide" is the far more comprehensive and detailed work, which is both its strength and its weakness. There is no better---in fact no other---book that discusses the variety of suicide methods in any significant depth. However the large amount of information comes at a cost: a suicidal reader may have a hard time extracting the data he wants from the mass of data he doesn't need. Similarly, the casual reader will probably find the quantity and details of evidence overwhelming.
The writing style is rather pedestrian, which doesn't detract much from a book of this sort, but occasionally slips into "medicalese" which does. On the other hand there are quite a few interesting and informative asides and digressions. These range from early Christian theological disputes, to minimizing heat loss in marine mammals, to the words of Jim Jones (remember Jonestown?) at an anti-suicide rally in San Francisco.
Given the sometimes-gory descriptions, the absence of photos and drawings is a bit surprising. However the author says in a "note to the reader" that these will be available on his website.
Overall, flaws and all, I highly recommend this book for anyone who has seriously considered suicide, or is presently contemplating it. With more reservations---the first half has too little detail, the second half too much---I would recommend it for general readers as well.
