Lord Cranmore, an aristocrat on his financial uppers, is anxious to sell a family diamond called the Angel s Eye and the Saint rides shotgun when Cranmore s employee Tom Upwater and his daughter Mabel go to Amsterdam to have the diamond cut. Tom delivers it to a jeweller called Jonkheer whilst the Saint entertains Mabel to the tourist sights. Then disaster strikes.

Tom prevails upon the Saint to break into Jonkheer s premises to retrieve the rock but the Saint is unsure of his true motive.
