The author of The Power Bug "trawls the murky depths of Cold War espionage and delivers gold" (Tom Kasey, author of Cold Kill).

The Russian space research center just outside Moscow is surrounded by searchlight and machine-gun towers; the inner perimeter fence is electrified and the place is strongly guarded by the KGB and by the GRU.

But Britain wants the secrets of the space bom being developed there, and the director of Britain's Special Security (Operations) Section has worked out a plan to get them.

James Dingle and Glyn Jones are briefed for the job. Undercover, they must try to unearth secrets of the Russian development for dropping warheads from a low-orbit vehicle. Posing as tourists, their mission is to find out as much as they can about this project.

But from the moment Dingle boards the plane for Moscow he is uneasy; he feels sure that he is being watched by the KGB. Has something gone wrong with the arrangements? Or is there a traitor in SS(O)S?

They'll have to get into the research center—and fast. They can't risk any tail catching up to them. There will be no margin for error . . .
