In 1949 John George Haigh admitted that he had murdered nine people, three of them complete strangers. In each case he opened a vein with a penknife, tapped off a glassful of blood, and drank it. He also liked the idea of drinking his own urine on account of the biblical text (John VII, 38) “He that believeth in me, the Scripture hath said, out of his belly shall flow rivers of living water.” It is well known that the drinking of urine can have a proudly erotic significance for some people. Havelock Ellis suffered (if that is the word) from urolagnia, as do a few writers to modern magazines such as “Forum”.
