Mike Shayne investigates a murder committed by an amnesiac Arthur Devlin wakes up so hungover that for a moment, he thinks the ship is sinking. As he gets his bearings, he realizes the only storm is inside his own head—and he isn’t on a ship at all. The last thing he remembers is being handed another drink at his going-away party. That was twelve days ago. Devlin has awoken in a sleazy hotel room, dressed in a stranger’s ratty clothes, with a bump on his forehead and a dead man at his feet. The phone rings: A woman who calls him Joey asks if he went through with the murder. Devlin has no choice but to say yes. To find out if he’s really a killer, Devlin hires Mike Shayne. Shayne has twenty-four hours to fill in the gaps of his client’s memory—and he will discover things that Devlin would rather stay forgotten.
