On doctor's orders, Bertie Wooster retires to the village of Maiden Eggesford but his rest-cure is interrupted by Aunt Dahlia who wants him to nobble a racehorse, Vanessa Cook who wants him to act as go-between for her and Orlo Porter - and Orlo Porter himself who would tear Bertie if he ever discovered that Bertie and Vanessa were once engaged.
