Margaret Murphy


A.D. Garrett is the pseudonym for prize-winning novelist Margaret Murphy working in consultation with policing and forensics expert, Helen Pepper.

Margaret Murphy has published nine internationally acclaimed psychological thrillers under her own name, both stand-alone and police series. She is  former Writing Fellow and Reading Round Lector for the Royal Literary Fund, a past Chair of the Crime Writers Association (CWA), and founder of Murder Squad. A CWA Short Story Dagger winner, she has been shortlisted for the First Blood critics award for crime fiction as well as the CWA Dagger in the Library.

Her lifelong passion for science is reflected in her painstaking research for her novels. In 2013, writing as A.D. Garrett, Margaret began a new forensic series, featuring Professor Nick Fennimore and DCI Kate Simms. Everyone Lies, which Ann Cleeves rated ‘thriller writing at its best?’, was a bestseller, and both Everyone Lies and the sequel, Believe No One, garnered starred reviews from Publishers’ Weekly. Jeffery Deaver commented, ‘A.D. Garrett has done for Manchester what The Wire did for Baltimore. And Simms and Fennimore are complex, compelling, and just plain marvellous.’

Truth Will Out, the third in the series, was published in November 2016. Helen Pepper is a Senior Lecturer in Policing at Teesside University. She has been an analyst, Forensic Scientist, Scene of Crime Officer, CSI, and Crime Scene Manager. As a Crime Scene Investigator, she examined over 10,000 crime scenes, ranging from thefts and fires to rapes and murders. Later, as Crime Scene Manager for Durham Police, she supervised CSIs in over 50 major incidents. She is a member of the Chartered Society of Forensic Sciences, and has a wealth of experience in the investigation of all crime types, from simple thefts to murders and terrorism.

An author in her own right, Helen has co-authored, as well as contributed to, professional policing texts. Her expertise is in great demand with crime writers: she is a judge for the CWA’s Non-Fiction Dagger award, and is Forensic Consultant on both the Vera and Shetland TV series, among others.
