Hi everyone, long time lurker, first time poster here…
Years ago I read a story about a detective, investigating a murder, who discovers that he committed the crime himself. It turned out he had a split personality. IIRC, the story was set in France at the end of the nineteenth century, and the crucial clue was a four-toed footprint.
Google turned up nothing, so I’m throwing myself on the mercy of the teeming millions - did this really happen, or was I taken in by fiction written in case-history style? Has a crime ever been investigated by the perpetrator?
I don’t know how to create a sig line so I’ll just say thanks.
