Claire Wheeler thinks her boss Lewis Enstone is being blackmailed. He has made regular payments to a firm run by John Hammel. Who runs a rival factory which has just grabbed a lucrative government contract.
The Saint takes an interest. Lewis Enstone is a middle aged man who has a great interest in toys.
Templar discovers that Enstone has been making payments to Harry Duggan (David Lodge) the trade unionists at Hammel's factory. It was payments to organise wildcat strikes.
Enstone wants to make sure that Hammel could not fulfil the government contract. So he,could do a hostile takeover of the firm.
Later Enstone is later found dead. Inspector Teal thinks it was suicide. Enstone found out his wife was cheating on her.
The Saint is convinced that the murder was arranged by Hammel and his business associate Albert Costello, an electronics engineer.
The story becomes a murder mystery halfway through. There are several suspects such as Enstone's cheating wife and her lover, but Templar has little doubt who the culprit could be.
