 Lieutenant Colonel Roger Fleetwood Hesketh TD , DL , OBE , was the son of Major Charles Hesketh Fleetwood @-@ Hesketh . Like his father , he was educated at Eton and Oxford before becoming a barrister , and later a soldier . Hesketh , then a major , joined Ops ( B ) alongside Jervis @-@ Read as the department 's only intelligence officer . Colonel John Bevan , in setting up the unit , felt that it would only require operational capabilities , and that intelligence would remain with his own London Controlling Section ; but with the arrival of Wild , Hesketh was handed control of an expanded intelligence section , which included his brother , Cuthbert , a civilian secretary and an MI5 liaison officer .
