Siegfried takes a close friend to task for wasting his own talents as a veterinary surgeon. Ewan Ross -- "the best horse man north of the Humber" has let his career slide gently into the whiskey bottle after the death of his wife. But Siegfried is determined to make use of his considerable skills. A valuable racehorse with a strangulated hernia could provide Siegfried with not only a way of striking back at "vets in Bentleys", but also putting Ewan on the straight and narrow. James, meanwhile, is strangely reluctant to take on responsibility for Mrs. Pumphrey's beloved Tricky-Woo when she announces that she is off to France. But Siegfried caves in under the persuasive skills of Mrs. Pumphrey and Tricky-Woo moves into Skeldale.
