Ever since she came face to face with a waxwork of Dr Crippen in Madame Tussauds’ Chamber of Horrors at the age of seven, DL Douglas has been fascinated by crime. So it’s fitting that her first historical crime series features real life Home Office Forensic Pathologist Sir Bernard Spilsbury, the man whose evidence sent Crippen to the gallows.

A former journalist, DL Douglas is also the Sunday Times bestselling author of the Nightingales saga novels, under the name Donna Douglas.
