A selective critical checklist of notable Monday TV:

Agatha Raisin & the Deadly Dance (streaming on Acorn TV): The delightfully blithe spirit, created by the late M.C. Beaton, returns with three new movie-length comedy-mysteries. Ashley Jensen (Ugly Betty) mugs charmingly as the former PR maven who's now a full-fledged private eye, operating a detective agency in the bucolic Cotswolds. In her latest case, Agatha follows up on a death threat to a bride-to-be, only for the would-be assassin to turn up dead.

The series is coming to HBO Max in May 2020, but until then, there are reruns.

Prodigal Son (9/8c, Fox): The season's most merrily twisted crime thriller scores again with the arrival of a so-called "Carousel Killer," who's got his sights set on the Whitly family: particularly a terrified Jessica (Bellamy Young), forced to follow diabolical instructions or another victim will be killed. While profiler Malcolm (Tom Payne) looks on, sister Ainsley (Halston Sage) is reluctantly pulled into the story with on-air TV interviews — including one with her deranged dad from jail, the notorious "Surgeon" Martin (Michael Sheen, enjoying himself immensely). It all builds to an impromptu and intense reunion of father (Martin), ex-wife (Jessica) and son (Malcolm) in the Surgeon's cell. Good times!

Friends (10 am/9c, TBS): Still a hot commodity in its 25th-anniversary year, the iconic sitcom returns to TBS as its full-time home — having left Netflix in advance of its streaming launch on the forthcoming HBO Max later this spring. In a month-long marathon (through March 6), Friends will air in order from start to finish with episodes airing weekdays from 10 am/9c to 4 pm/3c. Taking a break is not an option.
