H. H. Holmes has already taken us on quite the adventure. We know he got accused of committing insurance fraud with his mysteriously absent friend, Benjamin Pitezel; that three of the Pitezel children were also missing; and that he (eventually) accused his friend Miss Minnie Williams and her new beau, Mr. Hatch, of killing the children. His October 1895 trial resulted in a single guilty verdict for the death of Benjamin Pitezel, and Holmes hanged for it.
But he didn’t simply quietly wait out the rest of his life.
Let’s take a peek at the headline of the Philadelphia Inquirer on Sunday April 12, 1896.
He’s bumped up the number, certainly. At the trial Holmes was accused of a single murder – even the deaths of Alice, Nellie, and Howard Pitezel were not mentioned, since they did not happen in Pennsylvania. Now he’s progressed to “the greatest criminal in history” with 27 murders.
Granted, this is a newspaper headline. “The most awful story of modern times told by the fiend in human shape” is clearly meant to sell copies. They had advertised it in advance, too, to make sure they’d sell. Holmes had been paid for his story, and naturally the paper still wanted to make money on it. But we only know about Benjamin, Alice, Nellie, and Howard Pitezel. How did he get to 27?
First, he lied. Some of the people Holmes named actually came forward before his execution two weeks later to inform the world that Holmes had not, in fact, murdered them.
Second, he made other people up completely, either borrowing parts of names from people he did know, or not naming them at all.
And third … remember Miss Minnie Williams, who was supposed to be with the Pitezel children? Previously Holmes had said she was on the run for the murder of her sister, Nannie, but this new confession has Holmes murdering both of them. (Since neither sister had been seen since going to Chicago, these two seem to be likely instances of the truth.)
Holmes also used the paper to confess to murdering some of his mistresses, as well as one mistress’ young daughter. He varies the method from death to death, including suffocating unsuspecting victims in a large, room-sized safe that he had in his Chicago “Murder Castle.” So … Holmes completely qualifies as a serial killer, right?
Well …
He wasn’t done yet. After two spoken confessions, a written autobiography, and a further confession in the newspaper, he spoke his final words on the subject while on the scaffold. In spite of the 27 murders outlined in the Inquirer, Holmes’ final confession was only to two deaths, one of them a woman who died during an abortion. He argued that the real killer of Benjmain Pitezel had not been brought to justice and still needed to be found.
Then, after he was hanged, Holmes was interred in an extra-large coffin that had been half-filled with cement before he was laid inside. He had a clear fear of grave robbers – one that has been continually linked to his own role as a medical student and the ways cadavers were likely procured for lessons – and refused many offers of money for his brain or his body after his death. Once he was laid inside the coffin, more cement was put over him before burial.
But of course, the story didn’t end there. The world was far from done with the story of H. H. Holmes.
What I’ll do is write the idea down immediately. I’ve got plenty of notebooks –
This is my other notebook. It’s a
First confession in Boston, right after being taken into custody: at this point nobody was all that concerned about the children, so Holmes said that they were with their father, Benjamin. Who was totally alive. In South America somewhere, but totally alive. He had first stolen and then mutilated a corpse to be buried in Pitezel’s place.
This is also where Holmes switched from spoken explanation to written. Holmes’ Own Story, published before his autumn trial for Benjamin Pitezel’s murder, is a multi-part book that starts with Holmes’s autobiography. It continues into the second part which is meant to be his prison diary. Then, once the diary structure falls apart, he finally gets around to his explanation of how Alice, Nellie, and Howard could be dead … but it wasn’t his fault.
So 
Please meet H. H. Holmes. If you did actually meet him, though, sometime between his birth in 1861 and his execution in 1896, he might not have given you that name. He was born Herman Webster Mudgett and didn’t adopt the Holmes name until he’d completed medical school at the University of Michigan and then moved away from home (and his first wife).
Detective Geyer made use of the newspapers in his search of the various cities so that he didn’t have to keep explaining himself to various realtors. In Toronto, he gave an interview to numerous reporters so that the story of Holmes and the three children became front-page news. After this, he only had to walk in for the realtor to tell him no, he had never rented to anyone matching Holmes’ description – or that yes, he did indeed remember a man using Holmes’ favorite cover story. Geyer was able to speed through his list of realtors and find the house where Alice and Nellie had been killed.

Take my most intense process so far. A call went out for people who wanted to write about heroic criminals in American popular culture. A friend of mine sent it to me and I debated, but … well, rejection on a proposal hurts far less than rejection on a full paper, so I submitted. Even before something was really written, the two editors had their eyes on it.
Wilding published Jack the Ripper: Revealed in 1993 and an updated version (Jack the Ripper: Revealed and Revisited) in 2006. He starts with Mary Jane Kelly, the final victim of the Canonical Five, putting her in a difficult position. Wilding’s Mary is pregnant, and the father is the Crown Prince himself. For some reason, once she discovers her pregnancy, Mary goes to lawyer Montague John Druitt to inform him of her situation.
When they try to follow her one night, keeping track of Mary by her unique bonnet, Mary Kelly passed that bonnet to Mary Nichols in order to throw off her tail. She did not recognize Druitt and Stephen, and they did not realize that they killed the wrong woman. Thus Mary Nichols’ death was a case of mistaken identity. Mary Kelly worried that it was her bonnet that got her friend killed and told another friend, Annie Chapman. She also made the mistake of expressing the same concerns to Druitt and telling him Annie’s name, turning Annie into the second Canonical victim.
Finding it is usually the problem. Past Rebecca was good about making notes, but she also tended to write them longhand. Take a look here – these are my notes from my independent study course on Jack the Ripper’s victims from way back in 2011. The box is full. That’s a lot of information. And at least it’s divided by subject, with sources up front, and at least Past Rebecca had neat handwriting, but … that’s not the easiest thing to search. It’s a nice physical representation of the research that went into that paper, which turned into my first conference presentation and then my first book. Still, it’s not very user-friendly.
Oh, I still print things off. Here’s my notebook that I worked from while writing Ripper’s Victims. You can see some of my quirks – teeny font, two columns, printed sideways and then stuck in sheet protectors so I can scribble over it with markers. I find it’s easier to have the pages sitting by my laptop when I’m working on that specific section, and if you know me, you know I love my colored pens.
If you’ve only read one book about Jack the Ripper, chances are it’s Patricia Cornwell’s 2002 Portrait of a Killer: Jack the Ripper – Case Closed. Here she is on the back, examining a document carefully while wearing clean white gloves to apparently indicate she’s in an archive. Known for her fiction, especially her series about medical examiner Kay Scarpetta, Cornwell decided to use her personal wealth to investigate the Ripper crimes. Her research, which was updated first in a Kindle single and in a 2017 follow-up book, directed her toward accusing artist Walter Sickert as having been Jack the Ripper.
There are a couple issues here, in spite of how cool she might look on the back cover of the second book in her Matrix-style coat. First, her methods assume that the Ripper himself licked the stamps and the envelopes. This means both that the letter wasn’t handed over to an employee who sold the stamp and did the honors, and that the Ripper actually wrote the letters. And second, because of the age of the letters, only mitochondrial DNA could be tested. At best, mDNA showed that Sickert could not be excluded from the tens (or possibly hundreds) of thousands of possible people who could have licked the envelope. Cornwell’s experts told her she had narrowed the Ripper down to about 1% of the Victorian British population, and in her book she translates this as indicating that yes, it was Sickert.
In 2007, Russel Edwards bought the shawl at auction, believing the story of its provenance when other Ripper scholars present scoffed at the idea. Like Cornwell, he had DNA tests run, this time checking for matches to two people. (Again, note the CSI-style photographs.) Edwards concluded that the blood found on the shawl could indeed have come from Catherine Eddowes, and that the semen did not exclude his personal choice for Ripper, Polish barber Aaron Kosminski.

3. A progress keeper. This one is for Book Four, which is due to my editor in October, and it’s super pretty because it’s so consistent. Most of mine aren’t, but it’s important to keep track of your progress no matter what. When you’re just putting words into a computer, the only evidence that you’re actually doing anything is that you have to scroll a bit further in the file next time. I make up these little charts where each square is 500 words and I color it in at the end of the day to give myself that visual proof that I’ve at least done something.
