On a visit back to England, Jason finds himself with income tax problems. However, it turns out to be a way of blackmailing him into helping the police solve a series of robberies where the police computer seems to be illegally accessed.
Jason is summoned back from holiday to investigate a series of highly organized robberies by a syndicate called Crime-Con, who seem to be getting information from a police computer. Jason feeds it bogus information to report that a famous Bulgarian criminal - portrayed by himself - is arriving in town. He soon is introduced to the members of Crime-Con and discovers the mole within the police force assisting in the robberies.—don @ minifie-1
