Ten people. One island. Bodies piling up. Sounds like a party! From goodreads:

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.

This is a Christie novel without a detective, which I didn't know was a thing so that's a bonus!
