Jessica had taken the unusual step of hiring a Private investigator, to look into a historic case, the Danbury murder. Having no luck with contacting Judge Lambert, Archie Miles seemed her only option. Unfortunately Archie is murdered, prompting his partner Harry McGraw to compete with Jessica to solve the case.
I see others consider this story quite highly, and while I like the story, I find the execution of it rather messy, it's a little muddled in parts, and a little paint by numbers at the conclusion, the ending was a tad silly.
Praise though for introducing the character of Harry McGraw, Jerry Orbach really did perform well, a great on screen chemistry with Lansbury. Harry apart, I found the characters rather bland, somewhat unappealing, as always Lansbury shines through. 6/10
