A Wilderness of Mirrors

A senior SIS field officer has gone missing. Thornton is ordered to
investigate discreetly. He'd talk to a few people, invent some plausible,
probably bureaucratic reason. Check records. Pull back if anyone got
too interested.

He knew that Fisher, the missing man, was good. Good enough to do
things his own way, not the head office way, and get away with it. No
money troubles. No indiscretions. Balanced. No question of defection.

Thorton soon enters a maze of lies, obstruction and deception surrounding
an innocent German girl with extraordinary powers, KGB and CIA plots
and counter plots, an East/West kidnapping - and a spy with a conscience.
