Finished series 1 of "Unforgotten," a British mystery show about "historical" murders, which aired on PBS over the summer. It's quite well done, but the solution did feel a bit like it came out of left field.
One of the suspects was Bernard Hill, the captain of "Titanic" and Theoden in "Lord of the Rings." Another was Sir Tom Courtenay (Strelnikov in "Doctor Zhivago"), looking like Sir Alex Ferguson's doppelganger and sounding like Peter Sallis, aka Wallace in "Wallace and Gromit."
Anyway, if you like mysteries and have Prime, "Unforgotten" is worth checking out.
