First, there were ten - a group of strangers summoned as weekend guests to a private island off the coast of Devon by mysterious U. N. Owen, unknown to all of them, who 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 commited a big crime. One by one they fall victim to a serial killer, who, supposedly, is one of them. Before the weekend is out, there will be none. And only the dead are not suspected.
