The murder of a media mogul in his country mansion appears to be the result of his disturbing a gang of would-be thieves. The robbers are swiftly caught, but when they are unexpectedly moved to a different prison they escape. Back in Edinburgh, a young solicitor reveals to the press that one of the subjects had left a letter with her some time before the break-in which proves his innocence. Jack Parlabane, journo-extraordinaire, is intrigued, but when he approaches the lawyer he discovers someone else is trying to get near her—someone with evil intent, political connections of the highest order and a corrupt agenda.
