What is the connection between the number 13 and Jack the Ripper? Why was the number 18 crucial in catching Acid Bath murderer John George Haigh? And what is so puzzling about the number 340 in the chilling case of the Zodiac killer?

James Moore's Murder by Numbers tells the story of murder through the centuries in an entirely new way ... through the key digits involved.
