Synopsis
The receipt of a letter at 10 Downing Street, signed by an eminent atomic researcher and threatening to destroy the seat of Government by blowing up the Houses of Parliament unless the Prime Minister acts to bring his research work to an end, is at first dismissed as a hoax. But the drama grows when Scotland Yard discovers that the researcher has disappeared.
