By the time H. H. Holmes checked into Room 76 of the English Hotel in September 1894, he already had seduced and murdered at least two dozen young women in his infamous “Murder Castle” just blocks from the Chicago World’s Fair. He’d also run numerous insurance scams, operated several fraudulent businesses, and simultaneously juggled three different wives – all while leaving both police and his wives in the dark about his nefarious deeds. And if he hadn’t been so greedy for a $10,000 insurance check deposited in an Indianapolis bank, Holmes just might have gotten away with it all.
