The book that was voted the most popular of Agatha Christie's 80 crime novels in an international online survey held for her 125th birthday.

In 1939, Europe stands on the brink of war. Ten strangers are invited to Soldier Island, a remote rock off the coast of Devon. Cut off from the mainland and with their generous hosts Mr. and Mrs. U.N. Owen mysteriously absent, they are all accused of a terrible crime. When one of the guests suddenly dies, they realize that there may be a murderer among them.

The ten strangers include a reckless playboy, a troubled Harley Street doctor, an imposing judge, a rough detective, a ruthless mercenary, a God-fearing spinster, two anxious servants, a highly decorated general, and a nervous secretary. One by one, they are eliminated. Who will survive? And who is the murderer? Copies of a sinister children's rhyme hang in every room, with the murders mirroring the terrible fates of the 'Ten Little Soldiers'.

The clear winner of an international online poll to determine the most popular Agatha Christie book is being released simultaneously with a new three-part BBC TV adaptation featuring a stellar cast, including Douglas Booth, Charles Dance, Maeve Dermody, Burn Gorman, Anna Maxwell Martin, Sam Neill, Miranda Richardson, Toby Stephens, Noah Taylor, and Aidan Turner.
