Mark Griffin began his writing career when he was a teenager, with three successive years of gold medal awards in the Hampshire Writing Festival. In 1996 he moved to Los Angeles, where he turned his attention to acting, script writing and development.

After returning to England, Mark continued in this profession and was shortlisted in the top five out of 3500 entrants in a national crime thriller writing competition sponsored by Random House Publishing and the Daily Mail for his debut, When Darkness Calls.

When Darkness Calls, the first thriller starring criminal psychologist Holly Wakefield, was longlisted for the CWA New Blood Dagger Award.
