Flirtatious American blonde Miss Hailey Duke should never have accepted a summer weekend invitation to Fontaburn Hall. But when the Honourable Archibald Cooke Wellingham's house party are woken, in the early hours of Sunday morning, it's too late: Miss Duke's blood is on their hands. With the aid of Detective Chief Inspector Reynolds, Sergeant Ayari and loyal friend Dr Toby Cropper, Susie Mahl, on a timely commission drawing six racehorses nearby, seizes the opportunity to play detective for a second time. Her artist's eye for detail make her ideally suited to the task in hand, but is she getting carried away by her previous triumph - even to the extent of endangering her reputation and her relationship with Toby?
