Between 19 January and 6 March 1953, Christie murdered three more women he invited back to 10 Rillington Place: Kathleen Maloney, Rita Nelson, and Hectorina MacLennan. Maloney was a prostitute from the Ladbroke Grove area. Nelson was from Belfast and was visiting her sister in Ladbroke Grove when she met Christie; she was six months pregnant at the time of her murder. Christie first met MacLennan, who was living in London with her boyfriend, Alex Baker, in a café. All three met on several occasions after this, and Christie let MacLennan and Baker stay at Rillington Place while they were looking for accommodation. On another occasion, Christie met MacLennan on her own and persuaded her to come back to his flat, where he murdered her. Later, he convinced Baker, who came to Rillington Place looking for MacLennan, that he had not seen her. Christie kept up the pretence for several days, meeting Baker regularly to see if he had news of her whereabouts and to help him search for her.
