Labelled as 'The most colossal achievement of a colossal career.' by New Statesman, this is the world's best-selling mystery. Ten strangers, apparently with little in common, are lured to an island mansion off the coast of Devon by the mysterious U.N.Owen. Over dinner, a record begins to play, and the voice of an unseen host accuses each person of hiding a guilty secret. That evening, former reckless driver Tony Marston is found murdered by a deadly dose of cyanide. The tension escalates as the survivors realise the killer is not only among them but is preparing to strike again...and again... Narrator: Hugh Fraser
One minute, down and out actor Lorenzo Smythe was - as usual - in a bar, drinking away his troubles as he watched his career go down the tubes. Then a space pilot bought him a drink, and the next thing Smythe knew, he was shanghaied to Mars.
Suddenly he found himself agreeing to the most difficult role of his career: impersonating an important politician who had been kidnapped. Peace with the Martians was at stake - failure to pull off the act could result in interplanetary war. And Smythe's own life was on the line - for if he wasn't assassinated, there was always the possibility that he might be trapped in his new role forever!
