The Colorado Kid, Stephen King

On an island off the coast of Maine, a man is found dead. There’s no identification on the body. Only the dogged work of a pair of local newspapermen and a graduate student in forensics turns up any clues, and it’s more than a year before the man is identified.

And that’s just the beginning of the mystery. Because the more they learn about the man and the baffling circumstances of his death, the less they understand. Was it an impossible crime? Or something stranger still...?
