'Who Was That Man I Saw You With?' by Jeremy Burnham

Tara is assigned to test the security at a top-secret missile-defence system called Field Marshall – by breaking into the complex. But unknown to Tara, a villain named Zaroff is working on a scheme to frame her as a traitor, by making it appear that she is working with an enemy agent. As the evidence mounts up, Tara’s loyalty is questioned. But Steed, believing her to be innocent, investigates; it seems Tara’s innocence lies in the services of a lip-reader…
