"First, there were ten - a curious assortment of strangers summoned as weekend guests to a private island off the coast of Devon. Their host, an eccentric millionaire unknown to all of them, is nowhere to be found. All that the guests have in common is a wicked past they're unwilling to reveal - and a secret that will seal their fate. For each has been marked for murder, and one by one they begin to fall prey to an unseen hand. As the only people on the island, unable to leave and unable to call for help, they know that the only possible suspects are among their number. And only the dead are above suspicion."--BOOK JACKET.
