Sách nói: Secret of the Silver Car

Before he went to join the Armed Forces in World War I France, Anthony Trent had a successful secret 'career' as a master criminal in the USA, never caught by the police (see 'Anthony Trent, Master Criminal'). The war has just ended - but now Anthony Trent seriously fears exposure. While in the trenches, an explosion buried him alive, along with an English soldier. Thinking they would never get out alive, Anthony revealed his identity to the other soldier - just before they were rescued and separated. After recovering from his injuries, all Anthony can think about is finding the English soldier - to thank him for saving his life, but also to know whether the man will betray his big secret. His search is full of adventures, including espionage, blackmail and love. (Summary by Anna Simon)
