“FLESH AND BLOOD”
(PBS at 9 p.m., Sunday, Oct.4) This four-part “Masterpiece” series, a little more adultthemed than usual, stars Imelda Staunton as Mary, the nosy but friendly next-door neighbor to recently widowed Vivien (Francesca Annis), who has found new love with a gentleman (Stephen Rea) that her adult children (Claudie Blakley, Russell Tovey and Lydia Leonard) don’t exactly trust. The show is built around a tragic event that’s being investigated by a detective (David Bamber), dragging some family secrets out into the light of day.
