Trouble is on the way, however, for the Dolly Dobbs sparks off mighty passions: from rival inventor Thomas Bailey determined to beat it; from the Duchess of Dewbury who hopes to drive it; from Hester Hart, the famous lady traveller recently returned to England; from Lady Bullinger, leader of the club's racers?; from Hortensia Millward, leader of the Horse Against Motor Car Society and, indeed, it seems, from many others who frequent the club's London headquarters and motor stable. In the club's kitchens, Auguste Didier presents the members with a cuisine worthy of his position as master chef. But when hidden passions explode into hideous murder and Inspector Egbert Rose of Scotland Yard is called in, Auguste's other skills as sleuth are put to the test once more, as he battles to help solve the case.
