Martin Henderson was the Royal College of Veterinary Surgeons Inspector who visited Emmerdale Veterinary Centre in March 2018 after a vial of Ketamine was stolen from Vanessa Woodfield's veterinary bag. Vanessa was thrilled to find out Martin and Paddy Kirk were friends in veterinary school and as a result, Martin agreed to put in a good word for Vanessa. However, Paddy put his foot in it by joking about their other old friend, Maureen Taylor's facial hair - and Martin revealled she is his wife! Martin decided against putting in a good word for Vanessa and play things by the book instead. The RCVS later suspended Vanessa for a year.
