This show was a staple of my childhood - it seemed to be on repeatdly on Sunday afternoons on British telly in the late 80s and 90s! It's corny, wholly unrealistic and predicated on the notion that a retired teacher and mystery writer single handedly solves more murders than the FBI, but if you can suspend disbelief (and the gnawing suspicion that it's Jessica herself that's bumping all these people off - seriously if you were in town and Jessica turned up you'd run for the Hills knowing invariably at least 3 people were going to die!) then the show can be really fun, and a nostalgic throwback to a time when TV seemed simpler and the world somewhat less complex.
