Third in the mystery series with amateur detective Desmond Merrion.
> Detective-Inspector Young is detailed to investigate the mysterious death of the not very popular Sir Charles Formby in the cross-channel steamer Isle of Shepper. He is helped by his old friend Merrion and by his new friends, May and Frederick Brunton, the charming brother and sister who run the antique shop called Vallingfields. With Formby's death still unsolved, Young is switched on to the strange disappearance of the rather unprepossessing Mr. Pilkington, and finds that a lady of title is discreditably involved. Pilkington reappears - not to the best advantage - and Merrion promptly disappears....
