While convalescing from a near-fatal assignment in Mexico, Davinas lover, Colin Lomax, receives a secret report indicating a mole in British intelligence someone very high up. Someone who has sabotaged missions and blown operations for the past ten years. A mole so close to the top he can only bet racked down from the outside.
Davina, pleading disillussionment with a life of epionage, quits the Service to take a job with a prestigious advertising agency. Such, at least, is the cover she feeds Chief of Service James White.
Upon interrogating Peter Harrington the Russian spy who sabotaged Davinas mission in Moscow years earlier Davina discovers the report is true: Harrington hadnt operated alone. A second hand had manipulated events in the Service.
