The murderer of five-year-old Eileen Lockhart crept up behind her, put his left hand over her nose and mouth to stop her screaming, and raped her. Then he strangled her with his right hand. That was on Sunday, February 8th, 1948. Four days later Eileen’s body was found in a bombed-out building in Finsbury, north London, three miles from her home in Wellington Way, Bow.

A woman came forward with an odd story. She reported that while in a shopping queue she had heard a woman say that her husband had seen Eileen being dragged unwillingly along Finsbury Square and had almost interfered. Despite police appeals, neither the woman nor her husband were traced and nor, indeed, was the little girl’s killer.
