Despite being incredibly well-researched, the sweeping knowledge of the Holmes story laid out in this book proved to be quite stagnant. It might be said that Schechter's laborious efforts to retrieve every detail of this sordid criminal's past from 150 years ago resulted in a well-informed read, but one vastly different - indeed, far less scandalous - than readers come to expect.
I really felt this true crime "thriller" to be quite cumbersome. While it's a mark of a great writer to let sensational facts speak for themselves rather than to embellish upon them, I felt as if the entire Holmes story was packaged and sold as something it wasn't. I expected to read largely about the "Castle" and its many intricacies - stories of its design, its purpose, impressions given by those who had either stayed there as guests of the World Fair, or guests that had barely escaped with their lives.
And indeed while the 400+ page story does brush upon the Castle's horrors, that's about as far as it goes: truly, it maybe occupies 5-10 minutes of total reading time. The rest of the time? You're reading about some "otherworldly" man, the first known "multi-murderer" (because in the 1880s and 1890s, serial killers didn't yet exist) attempting to pull off a $10,000 insurance fraud scheme (equivalent to about $400,000 in today's money). It was well-researched, as I said, I've got to give the author that much credit.
I suppose I just expected to hear more about the evils within the man and truly astonishing feats of cleverness he'd managed to pull off; not minute day-to-day details of his shuffling around of people, all in an attempt to hide the murder and defrauding of his friend, and this information instead being masqueraded as evidence of the clever, "brilliant" man able to disarm even the most intelligent, well-bred young woman with his wicked, scheming ways.
Although I don't think Schechter went obnoxiously far as some true crime writers do in glorifying their villain at the expense of his (usually female) victims, I do think that he gave Holmes a bit too much credit, considering that:
1) it's the late 19th century we're talking about here, people... it didn't exactly take a mastermind criminal to pull off things like fraud and murder, given the absence of today's technology with computers and forensics.
2) it seems doubtful that all the women are really that susceptible to his charms; rather, in this era, they simply had no choice but to defer to the man of the household. therefore, any "manipulation" the author or the press of that day may have claimed Holmes pulled over these women - especially, for instance, Carrie - really should be attributed to his ability to manipulate their male counterparts (such as Carrie's husband).
It's not as if Carrie had a choice after Holmes and her husband hatched the plan and once her husband went missing. The husband seemed infinitely more gullible and ready to swallow Holmes's lies wholesale, while she was clearly just exhausted and desperate. As for the rest, again, it's too hard to tell in that era, where women didn't exactly assert themselves the way they might today.
All in all, while it is great to finally hear the full story with great sources to back it up, it doesn't change the fact that the book was about 150 pages too long, and overly bogged down in unnecessary characters and details.
I'd recommend if you want all of the true facts of the case, but don't expect to be on the edge of your seat. He was indeed a disturbed and sadistic criminal, but not exactly an extraordinary criminal (save for in his own mind, anyway). A lot of people will prefer to skim through it, rather than read every tedious word.
