In a spine-tingling mystery, death follows TV network sleuth Matt Cobb to Bermuda A cruise ship full of mystery writers may sound like a fantasy for some, but for Matt Cobb, whose job consists of untangling serious knots for a large television network, it's anything but--especially when it results in a real-life murder to solve.   Cobb is snatched from his normal duties at the network and put on a boat to St. David, to act as minder for two winners of a radio contest. The winners happen to be attractive women, a small bonus, but Cobb can hardly enjoy his time with them before a macho writer takes an active dislike to him and a corpse appears. And when some kitchen knives go missing--along with quarreling writer Lee Schaeffer--and other killings and disappearances ensue, Cobb ends up looking to a visiting Mafia boss for clues. But to get to the truth, he will have to work his way through the theories of amateur sleuths and save his own neck.
