Diana Rigg can act -- and act and act. And as fondly as she might be remembered for her work as Emma Peel in "The Avengers," the extent of her acting talent is going to be the great revelation for some viewers of "Mother Love," the three-part chiller that kicks off "Mystery" at 9 tonight on Maryland Public Television (Channels 22 and 67).
The first thing "Mystery" fans need to know is that "Mother Love" is not the standard mystery with a dead body, red herrings, suspects and clues. But "Mother Love" is loaded with mystery and suspense of the psychological kind.
It is the kind of mystery and suspense Alfred Hitchcock was so good at providing. We are presented with a mother who appears initially as all goodness, love and propriety. But soon we see the little cracks in Mom's facade, little irregularities that suggest she might not be all that she seems. After a while, the cracks become gaps, and we come to understand that Mom's love is obsessional and her homicidal impulses have her headed down the highway that runs past the Bates Motel. Meet Mrs. Mom, the murderer.
