The rather disgruntled pair of Tommy and Tuppence are sequestered in the Grand Adlington Hotel, having made a pig's ear out of their latest case. But, while mournfully sipping cocktails, with Tommy oddly dressed as a parson, they are gleefully accosted by their old acquaintance Mr. Bulger, who has London's most beautiful stage actress, Gilda Glen, in tow. Featherbrained and a little confused, Gilda takes Tommy for a real clergyman and scrawls out a desperate note to meet him away from the hotel. While Tommy and Tuppence mull over the note, in storms an old flame of Gilda's, claiming he wants to wring someone's neck. When the duo turn up at the meeting place, all hell breaks loose.
