D.M. Mark is the historical alter ego of David Mark, who was a crime journalist before becoming a novelist. He has written six novels in the McAvoy series: Dark Winter, Original Skin, Sorrow Bound, Taking Pity, Dead Pretty and Cruel Mercy, as well as two McAvoy novellas, A Bad Death and Fire of Lies, which are available in ebook. Dark Winter was selected for the Harrogate New Blood panel and was a Richard & Judy pick and a Sunday Times bestseller. The Zealot's Bones is his first historical crime novel. He chose to delve into the past after deciding that some stories served up by his twisted imagination are just too disturbing to feature in the present.
He lives in East Yorkshire and you can find him on Twitter @davidmarkwriter.
