Thursday’s Mystery Marathon: Hailey Dean, Picture‑Perfect Puzzles & More

If you’re hunting for a good mystery on Thursday, the lineup on GREAT! Mystery is a solid buffet of classic whodunnits and fresh twists. Below are the headliners and a quick rundown of what to expect.

The Main Event – Hailey Dean Mystery: Deadly Estate

08:10–09:06 BST – The first half‑hour is the flagship of the channel. Kellie Martin’s character, a prosecutor‑turned‑therapist, finds a client’s estate sale turning into a homicide investigation. It’s the kind of steady pacing that keeps you guessing without feeling rushed. I think it stays reliable for fans of procedural drama.

Picture‑Perfect Mysteries: Dead… (Diamonds)

10:10–11:06 BST – Alexa PenaVega stars in a jewel‑theft caper that blends a slick visual style with a classic mystery setup. The show offers a fresh feel, but I’d say it holds up well for viewers who like a bit of glamour with their whodunnit.

Unforgettable & In Plain Sight

12:00–13:00 BST – Unforgettable brings a new case each night, and this episode promises a chilling twist. 13:00–14:00 BST – In Plain Sight continues its political thriller vibes with an episode that adds depth to the series. Both are solid choices if you like a mix of personal drama and investigative intrigue.

Castle & Diagnosis Murder

14:00–15:00 BST – Castle offers a light‑hearted self‑contained mystery that is still entertaining. 15:00–16:00 BST – Diagnosis Murder’s “Casanova Killer” episode is a classic detective story that keeps the suspense alive. Both fit nicely into a late‑afternoon break.

Murder, She Wrote

17:00–19:00 BST – Two episodes of this beloved series offer a nostalgic feel. The pacing is slower, but it’s still a reliable pick for long‑time fans.

Late‑Night Thrillers

23:55–01:50 BST – Hailey Dean Mysteries: A and 01:50–03:20 BST – Fatal Justice provide a darker, more intense mood for those willing to stay up late. They’re good for viewers who prefer a bite of suspense after midnight.

Bottom line: The Thursday schedule on GREAT! Mystery is a well‑rounded spread of classic and contemporary mysteries. Pick the shows that suit your mood – whether it’s the steady pace of Hailey Dean, the glamorous twists of Picture‑Perfect, or the late‑night thrills of Fatal Justice.
