Cruising for a killing. Take a gorgeous companion for a leisurely sail on a beautiful yacht. Sounds like easy duty for Matt Helm - except that the last three captains of the yacht died under mysterious circumstances. The next time sharks circle the boat, Matt had better be ready - if he wants to stay alive. It's an assignment that will have Matt tangling with a crew of dangerous women . . . an Arab terrorist squad . . . AND an elite organization of death-dealing specialists, led by a suave psychopath with very personal reasons for wishing Matt Helm serious harm . . .
