The Secret Adversary (Unabridged‪)‬

Described as an "excellent yarn", "amazingly clever", and a "thrilling adventure", Agatha Christie's tale of a dauntless pair of amateur detectives, Tommy Beresford and Prudence "Tuppence" Cowley, who stumble upon a puzzling mystery, was recently adapted for a BBC TV series that will air in 2015. The story begins on the doomed RMS Lusitania and takes the listener through a web of intrigue, murder, and mayhem.
