Paul Temple and the Harkdale Mystery

It wasn't quite an ordinary robbery. The bank lost 42,000, and a policeman lost his life, and the robbers were caught almost immediately.But in the bag where the money should have been there was only a copy of the Concise Oxford Dictionary. And in the garage where Paul Temple's car should have been there was the body of a dead robber.Which in itself was enough to send our hero off on one of the strangest cases of his life. One that took him deep into the bowels of the underworld and placed him face to face with Mr Master Mind.
