Travis McGee is too busy with his houseboat to pay attention to the little old man with the missing postage stamps. Except these are no ordinary stamps. They are rare stamps. Four hundred thousand dollars worth of rare. And if McGee doesn't recognize their value, perhaps Mary Alice McDermit does, a six-foot knockout who knows all the ways to a boat bum's heart. Only it's not McGee's heart that's in danger. Because a syndicate killer has put a contract on McGee. A killer who knows something about stamps . . . and even more about McGee.
