The Grantchester Mysteries: Sidney Chambers and the Persistence of Love by James Runcie
Life is never straightforward when you're a full-time priest and part-time detective. So when a walk in a bluebell wood takes an unexpected turn, Archdeacon Sidney Chambers finds himself plunged into another murder investigation: who would want to kill a harmless old hippy - and why was the man foraging for poisonous plants?
Sidney's findings soon lead him into sunny Granchester's dark underworld, where love is free and motives are shady. But his investigation, together with his continual inquiry into the divine mysteries of life, love and family, is blown apart by a devastating loss that will change his world forever.
