Octavus Roy Cohen’s The Corpse That Walked is an interesting book. A man who wants to help his fiancée with a debt takes a shady but well-paid job doubling for a millionaire investor. He’s instructed to be highly visible to press and public in Miami Beach while the rich man goes quietly to South America, where his newly rented anonymity will allow him to ace competitors out of a profitable minerals deal. The only problem is it’s all a lie. The rich man is about to be indicted for various financial crimes and faces years in prison, so he’s found a double with the intent of having him murdered. Thus freed from federal pursuit, the rich man plans to adopt an entirely new identity. Plastic surgery figures prominently in the narrative, so if you accept that one man can made to look like another, this is reasonably entertaining stuff.
