Found - a sensationalist paperback The Christie Case (Gaywood Press, London circa 1958). A rare non-fiction pulp by Ronald Maxwell - one of the youngest journalists following the case. The book begins:
The Christie case was more than the stories below the headlines for me.It was the story behind the headlines and it took many sleepless nights and long-drawn days to unfold as I followed closely upon the greatest manhunt of modern days, culminating in the final arrest of a man named John Reginald Halliday Christie, in whose flat the partly clothed bodies of four women were found strangled.

By accident, the man tapped against the wall, and there was a hollow sound. It intrigued him. He tore away a strip of wallpaper and discovered a small hole in the partition which his action had exposed. Through the hole, in the small cavity inside, he saw a woman's leg. Shaken with horror, he looked closer. There, in the dark hollow, he could see well enough to distinguish the outline of a partly clothed body. In his brief glance it up in the fact that there were two bundles behind the body.
… He ran excitedly into the street in search of the police, it was not difficult to find a constable in this part of the Royal Borough of Kensington... within minutes, the whole apparatus of Scotland Yard been set in motion in motion and the hunt had begun...
