from the publisher:
Travis McGee is a self-described beach bum who won his houseboat in a card game. He's also a knight errant who's wary of credit cards, retirement benefits, political parties, mortgages and television. He only works when his cash runs out and his rule is simple--he'll help you find whatever was taken from you, as long as he can keep half.
It's on this list of 100 favorite mysteries of the century, which is how I found it.
