Imogen won the Telegraph’s ‘First thousand words of a novel’ competition in 2007 with the opening of Instruments of Darkness, her first novel. Her other novels in the Westerman / Crowther series are Anatomy of Murder, Island of Bones and Circle of Shadows. Her new book, not part of the series, is called The Paris Winter and will be published in spring 2013.
