By far the best hour so far: grown-up, believable and full of suspense.
It's an excellent performance by Richard. He goes through a whole range of emotions in this story, and all of them are very convincing. I particularly loved the scene where he looked like he was about to burst into tears in the lounge but didn't. Very nicely acted. Some great support from Will and Judy as well.
After a few references in earlier episodes, we finally get to meet the Baldwin sisters, and despite looking notably younger, they're just as scatty and detached as they will be throughout the series. I'm guessing they were characters in the original book as they're also mentioned in the Spencer's Mountain film.
Ep and Mary-Ellen's hunt for the typewriter is brilliant. I was genuinely surprised they found it in the end. Of course, being in an antiques shop, there's a fair chance the Baldwin ladies would have stumbled across it themselves in the end.
This is the first episode which takes place on a specific date. The news report of the Long Beach earthquake places it on 10th March 1933. It thus takes place before the Carnival episode, which refers to the Chicago World's Fair - an event which did not begin until May that year.
