On February 8, 1983, a plumbing engineer arrived at an apartment in Cranley Gardens to investigate a blocked drain. When he opened the drain cover, he knew right away that the smell was not anything that would usually be in a pipe . . .and he pulled out large pieces of flesh. It was traced back to the top floor, where lived 27-year-old Dennis Nilsen. When he was arrested, Nilsen was discovered to have murdered at least 13 people - but even Nilsen couldn’t remember how many.
