This is a response to the author of the question referring to the episode of Alfred Hitchcock concerning the nurses in the old house...This episode first aired on "The Alfred Hitchcock Hour", February 15, 1965, and was entitled "An Unlocked Window" and starred Dana Wynter as Nurse Stella Crosson, who is hired as a companion to an invalid, and is aided by another nurse Betty Ames; it turns out that Betty Ames is really a man at the end of this frightening episode....for complete information as to story, etc. of this episode refer to the TVTome.com site and look up the Alfred Hitchcock Hour series; I am sure this is the one...I too was scared out of my wits, but was also quite young when I saw it for the first time; it is really quite well-done and deserves re-airing, as I don't think this series is being aired at the present time. For everyone's information, I believe the first season of Alfred Hitchcock Presents will be available some time this year, I believe for the 50th anniversary of the show; I do hope it contains a lot of good extras.
