The Doctor Blake Mysteries

Blake is called to investigate the murder of a retired carpenter, a case that quickly centres on a single potential perpetrator. The only viable suspect is a teenage boy who was found kneeling in prayer over the body, his clothing smeared with blood.

Measure Twice is a programme presented in the form of a single episode. It belongs to the episode‑type genre and follows the series’ usual format of focusing on a self‑contained investigation. The show’s structure allows a concise, tightly‑woven story that centres on a particular case, and this installment stays true to that style. In this episode, Blake is summoned to look into the killing of a retired carpenter. The investigation quickly narrows down to one plausible perpetrator – a teenage boy who was discovered kneeling beside the body, apparently praying, with his clothes stained in blood. That boy becomes the focal point of Blake’s inquiry, as no other viable suspects emerge from the initial evidence. The boy’s presence at the scene, his apparent reverence, and the fresh blood on him make him the sole realistic suspect in Blake’s eyes. As the case unfolds, the investigation hinges on determining whether the teenager’s actions were those of a guilty party or something more ambiguous. The episode therefore concentrates on Blake’s effort to untangle the circumstances surrounding the carpenter’s death, using the boy’s unusual behaviour as the key clue.
