Another of Len Deighton's spy novels, published in 1966. Sucks you into its densely-complicated plot and leave you wondering, "What the hell is this, man?" "Moves like a giant jetliner and hits the mood of the vicious Sixties with deadly accuracy"...or so someone said at the time. Supercomputers, New York, the KGB, biochemical warfare, a teenage assassin, Finland, and that nameless secret agent narrator who wears hornrims.
