By mid-February 1965 the Police in London had six young women who had been murdered in a short space of time. Two other women had been murder in the years prior to this, an as February 1965 came to a close, they hadn't been connected, yet.

At the head of the investigation was Chief Superintendent John Du Rose. A seasoned detective approaching the end of his career. A career that had seen him involved with such infamous characters of John George Haigh, the acid bath murderer. Over the course of his time in the police he had developed a reputation for the rapidity with which he solved complex investigations. He had even earned himself the nickname of 'Four Day Johnny' - the efficacy of his methodology has since been questioned. None more so than during the investigation into the Hammersmith Nudes, but we will return to that matter later. For now, at least, we will stay in 1965.
