From NetFlix:

Just when everyone thought she was down for the count, lost to drugs and unable to afford anything, Irish folk singer Maggie Sheridan (Helen Mirren) avenges the death of her landlord, who was killed for her vast art collection. Unable to let the criminals literally get away with murder, Sheridan pretends she’s an art dealer and hunts them down. Along the way, she pulls her wrecked life together and even falls in love with a dashing count.

Masterpiece Theater offered this Helen Mirren drama in two parts. Kathy and I needed at least 3 sittings to get through the more than three hours. But it was worth the effort. All the actors, including Helen Mirren, do a wonderful job. At one critical point you think the story is over, but it continues on in a significant way. There are a few murders but the gore (including blood) is minimal. As usual Kathy hid her eyes in the really suspensful parts. See if you can recognize which actor plays the dashing count.
