Perry hires a temporary typist who flees in a panic, leaving behind a pair of diamonds hidden in a wad of chewing gum.
Down the hall from Perry's office, a co-owner of a gem importing company has been charged in a smuggling scheme, and with murdering his accomplice.
Mason agrees to defend the accused man, who would rather die than cooperate.
And he just might--unless Mason can track down the terrified typist.
