At the centre of the church’s twisted mythology is the story of the Drowned Prophet, Daiyu, believed to be divinely reincarnated.“While Strike gains valuable insights from former members on the outside, Robin finds herself facing unprecedented psychological and physical duress on the inside. Solving the mystery of the Drowned Prophet’s death becomes key to the case but leads the detectives into dangerous, uncharted territory.”‌The series has been highly praised over the years, with many calling it a must-watch. One person said: “Excellent cast, dynamic storyline, unique cinematography, all combine for an outstanding series.

I really enjoyed watching this show. Each series within the series had a new mystery, bringing about a need for great investigative instinct to solve the mysteries presented. The episodes were complex with twists and turns along the way.”Article continues belowAnother added: “Brilliant. All I can say is watch it. I watched the first three episodes. In one go, it was that good. I was only going to watch one, but it got me hooked immediately. The acting was brilliant, Tom Burke, who I have to admit I've never seen before, played a brilliant part. He was like a young modern-day Columbo. The storyline had you guessing from the start, and there was a great twist at the end. 10 out of 10."All series of Strike are available to watch on BBC iPlayer.
