In They Came to Baghdad, Mr George Hamilton Clipp is the husband of the woman whom Victoria Jones accompanied to Baghdad. According to Miss Spenser of St Guildric's Job Agency, Mr Clipp had called from the Savoy Hotel asking for someone to accompany his wife, who had broken her arm, to Baghdad. Mrs Spenser thought the post might be suitable for Victoria and referred her. Victoria subsequently met Mr Clipp at the reception desk of the Savoy and he took her to be interviewed by his wife.
Mr Clipp is described as an immensely tall and very thin grey-haired American "of kindly aspect and slow deliberate speech".
Much later, Victoria would discover that the couple are in reality agents working for the a secret organisation called "The New Order". This couple had the particular mission of luring Victoria and getting her to go to Baghdad. They may or may not have been a married couple.
