Ian Rankin Investigates: Dr. Jekyll & Mr. Hyde

Stevenson had always suffered from nightmares - they began as a child growing up in Heriot Row, Edinburgh. Over and above Cummy's tales, which it is believed included other infamous Edinburgh characters such as grave robbers Burke and Hare and Deacon Brodie, Edinburgh itself is also credited as being very much part and parcel of Stevenson's inspiration for his creation. The "two sides" of the city with the New and Old Town - where Stevenson consorted with prostitutes - also fueled his imagination and helped create the Jekyll and Hyde legend.
