Publication: Victor Gollancz Ltd, 1977, London
First edition. Fine in price-clipped dust jacket. A title that quickly established itself as a classic not only for it's use of most bizarre methods of killing but also for the locked room mystery at the heart of the story. The victims were all members of a little group called the Seven Unravellers--seven detective story fans. The author has since gone on to make a name in science fiction. Scarce.
