And Then There Were None by Agatha Christie

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. One by one they fall prey. Before the weekend is out, there will be none. And only the dead are above suspicion.
