Keeler, Harry Stephen, 1890- Big river trilogy ##2

Several men find themselves stranded by a flooding river on Bleeker's Island. The jewels known as Cleopatra's Tears are missing, and one of the men is believed to be Actor Hart, notorious killer and thief - maybe even the one who stole the jewels. Can the sheriff figure out which one is Hart - and make sure he's the one without a life jacket when the dam upriver gives way?
