Harry Stephen Keeler is a writer many mystery fans have never heard of — but once you step into his world, it’s hard to get out. Riddle of the Travelling Skull is one of his most famous (and most unhinged) novels, a book that reads like something Agatha Christie might’ve written... on LSD.
The story follows Calthorpe, who accidentally switches suitcases on a train trip to Chicago. Back home, he opens the suitcase only to find — a skull. Inside it: a bullet, mysterious papers, and clues that lead him down a bizarre investigation involving theft, murder, and deception.
We learn that a man named Phalmsey had stolen $20,000 from a gambler, and his friend Pelton — instead of reporting him — decided to kill him and take the money for himself. Things grow even more tangled when a man named Payne appears, demanding $20,000 in exchange for the skull, which could be used as evidence to send someone to prison for life.
During their conversation, Payne reveals that he is actually Phalmsey — he had foreseen Pelton’s murderous intent, jumped into a river, escaped to London, and found an almost identical skull to fake his own death and later blackmail Pelton for the stolen money.
But in the final twist, when Calthorpe lights a match in the darkness of the park, he sees that the man he's been speaking to isn’t Phalmsey — but his old friend, John Barr. What this means exactly remains unclear. The mystery is unresolved. The novel ends in a way that may seem either nonsensical or brilliant — depending on your patience and your tolerance for chaos.
To be honest, I was a bit disappointed by the ending. The final twist — where the mysterious blackmailer turns out to be John Barr, a relatively minor character — raises more questions than it answers. If it really was Barr, how could he have known all the intricate details about Phalmsey, Pelton, the stolen money, and the skull?
One might argue that Keeler was more interested in creating a dizzying narrative than in resolving it. The novel leaves you with the sense that the answer is just out of reach — or that maybe there was never meant to be one at all.
Still, the book is an experience. For readers who enjoy strange logic, relentless twists, and narratives that feel like dreams verging on nightmares, Riddle of the Travelling Skull offers a truly unique ride — even if it doesn’t quite take you to a clear destination.
