Detective Sergeant Aaron Fowler of the Metropolitan Police doesn’t count himself a gullible man. When he encounters a graphologist who deduces people’s lives and personalities from their handwriting with impossible accuracy, he needs to find out how the trick is done. Even if that involves spending more time with the intriguing, flirtatious Joel Wildsmith than feels quite safe. Joel’s not an admirer of the police, but DS Fowler has the most irresistible handwriting he’s ever seen. If the policeman’s tests let him spend time unnerving the handsome copper, why not play along? But when Joel looks at a powerful man's handwriting and sees a murderer, the policeman and the graphologist are plunged into deadly danger. Their enemy will protect himself at any cost--unless the sparring pair can come together to prove his guilt and save each other.
