This week Zoe Henry, better known as Emmerdale vet Rhona Goskirk, uncovers the astonishing story of a local Yorkshire vet whose life was transformed by the Great War. Aged 55 at the outbreak of war, Joseph Abson was driven by his love of horses to serve in the front line and in the process would go on to change the course of veterinary science. She may be very used to playing a vet, but it’s quite a reality check for Zoe when she’s faced with the real demands of the job. From getting hands on at a dairy farm to observing pioneering equine surgery, Zoe finally faces her fear to prepare a skittish war horse for Emmerdale’s big parade. Charting Joseph’s career from family practice to post war super vet, can Zoe uncover what happened in the battle fields of France to leave him honoured by the king and one of the most distinguished vets in Britain?
