I vaguely remember this series. I do remember it was a fairly well written series. I can't remember any episodes except for one with Mariette Hartley. She played a mom who had a young son. I forget why she didn't have a husband. Widow? Anyway she was a mystery writer who wore a handmade deerstalker. Any way she takes him on vacation by a lighthouse. He stumbles upon an interesting mystery. He gets help from mom. It was upbeat and a fun episode. I wish I could watch it again.
