I don't know why the Summary and Show Book state that Addison Blake was "a man who was never married". More precisely, at the beginning Floyd Grant claims that Blake never had any children and also was never married. Later in the first half Della provides more information about all this. And, there was an explosion early on at Ladera Farms, but the early plot exposition does not mention a bomb--the idea was to make the explosion look like an accident.

I've taken the liberty of correcting the plot summary. -Submitted by 10yearoldfan, 21 October 2013.

Hey! Is that the ceiling fixture from Perry’s office hanging in that motel room?

How foolish for a young woman to go roaming around unescorted in a strange town. Submitted by 65tosspowertrap, 11/8/2013.
+ And just as foolish for the motel owner to hand over his keys to Linda Blake. OK, she's really cute, I get that -- but she says her driver's license is "from England," where they drive all wrong. JohnK, 21 October, 2015
++ How foolish also for a young woman in a foreign country to litter (drop the telegram envelope on the ground), except that it allowed the hotel owner to pick up the envelope to find out where the young woman was going. jfh 20Dec2019

When the DA is questioning Charles Lambert on the stand, it is taken at a strange angle--from below him, with a blank wall behind him. I wonder if that had to be re-shot later, and they didn't want to get extras in to fill the court again. --yelocab 26FEB18

Spoiler Warning! Do Not Read Below If You Have Not Seen The Episode

First of two sequential episodes where the victim really had it coming. In this episode the killer confesses that she shot the victim on impulse after he had boasted of just having murdered her husband. Submitted by cspoleta, 5 March 2017
+ Correction: she did not shoot him, she hit him with a walking stick. jfh 15Apr2019.
Was that a black pocket square Charles Lambert wore on the stand? Unusual looking.
