More information
Tonight Castle returns to the precinct with a case that feels more like a forensic puzzle than a murder mystery. A bomb detonates at an anti‑capitalist rally, killing five and sending shockwaves through the city. The FBI steps in, relegating Beckett and Castle to background work. Captain Gates, desperate for fresh eyes, asks Castle to apply his novelist’s knack for timing. Together they rebuild the 47 seconds before the blast, tracing a suspect’s movements, a misplaced bag, and a hidden trigger. Beckett’s police instincts clash with Castle’s theories, while the pressure builds as the team races against a possible copycat. The episode weaves tense interview scenes with a meticulous timeline, culminating in a reveal that puts the detectives in the line of fire. Nathan Fillion and Stana Katic keep the banter sharp, even as the stakes get personal.
Castle broadcasts on Great! Mystery at 11:10am, Friday, 19 December 2025.
