The Deep Blue Good-By (Travis McGee, #1)
TRAVIS McGEEHe's 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.
