A plane crash reveals that a canister of uranium 235, one-half of an atom bomb, was being smuggled into England. Peter Brady has a theory that this is part of a plan to launch another world war – that atom bombs are being placed under the capitol cities of the world during the peace years.

Peter believes the other uranium half is already in London somewhere, just waiting to be combined and detonated by a foreign power, and embarks on a search to find the source of the parts.
