The Angels Will Not Care (A Cecil Younger Investigation #5) - John Straley

Cecil Younger never thought it would come to this: providing surveillance for a chicken coop being raided by a fowl thief. But things have not exactly been breaking right lately for the Alaskan P.I. The logical thing to do? Take a vacation, of course. Well, it''s not exactly a vacation. Younger has been paid to investigate a doctor aboard a luxurious cruise ship up the Alaskan coast. Except passengers are dying. Now Younger finds himself trapped on a ship of fools with a murderer who is leaving a trail of well-to-do passengers in his wake... and leaving evidence pointing to Cecil!
