Peter Larner did not publish his first book until 2009, with the opening novel in the Jack Daly series of mystery thrillers. Lost in a Hurricane was followed by Deathbed Confessions and The Unfolding Path. The fusion of actual and fictitious events used in Deathbed Confessions, also produced an utterly convincing storyline in the author's historical novel Farewell Bright Star, an imaginative retelling of the first love and last days of the English poet John Keats as seen by his friend, the artist Joseph Severn. In 2013 a new collection of mysteries was created by the author. Covenant of Silence introduced forensic police officer Cally Boyce and her colleague, the ageing Detective Inspector Ashley Bertoni. The second in this thriller series is Covenant of Retribution, a story that establishes Boyce and Bertoni as an unlikely duo, but a force to be reckoned with.
