David Mulholland was born in Kingston, Ontario, Canada, and raised in the Ottawa Valley town of Arnprior. He now lives in Ottawa.
Mulholland began his writing career as an advertising copywriter in private radio. He went on to work as a researcher, story editor and interviewer for CBC Public Affairs television, a general-assignment reporter and music reviewer for the Ottawa Citizen, a syndicated country-music columnist, a part-time stand-up comic with Yuk Yuk’s, and a speech writer for a number of departments in the federal government.
During these years, Mulholland wrote fiction when time permitted. In the spring of 2001, he began devoting full-time to writing a novel. The result is McNab, which was published by General Store Publishing House in October 2006. DUEL, his second novel, was published in October 2009. He is currently working on the next one.
