Another fine acting-turn for the always-watchable Robert Harris. Interesting, also, to see him paired with the excellent-actress Jessica Tandy, of much-later "Driving Miss Daisy" fame. This was an especially-interesting episode for me in that it's set in the early 20th-century--1910 New York City to be precise--a rather-refreshing break from "modern" settings & stories. There have been other exceptions in the Hitchcock-series, too, such as "The Older Sister", set in late 19th-century New England, a tale based on the Lizzie Borden murder-case. Tandy, though quite-attractive here, convincingly-looks every-inch the 1910 spinster. Harris portrays a "nice" character here. Tandy is "nice", as well, but upon her arrival, quickly-reveals that something's amiss with her mentally. I won't rehash the plot but this is an effective-episode, one that builds, not so-much suspense, as curiosity as to just what's going-on with Tandy & her mounting-paranoia over her baby. Harris is quite-mystified by her strange-outbursts & nervous-behavior but ultimately is sympathetic to his intended's plight. Tandy, by program's end, becomes understandable. Harris, though, is devastated by realizing that he's largely to blame for her predicament. Nice twist at finale, whether one guesses it early-on or not. I, for one, didn't. A different kind-of Hitchcock-episode, especially-good because it IS different!
