Brown, a native of Edinburgh, was last seen alive on 23 October 1964 by a colleague who saw her get into a client's car; on 25 November her body was found in a car park on Hornton Street, Kensington. She had been strangled. The colleague was able to provide police with an identikit picture and a description of the car, thought to be a grey Ford Zephyr. Brown had testified as a witness for the defence, along with Christine Keeler and Mandy Rice-Davies, at the trial of Stephen Ward in July 1963.
