I have to comment.  My goodness, what an incredible talent Agnes Moorehead was.  She does not get enough credit, honestly.  I've listened to hundreds of RMTs, and this is my absolute favorite solely because of how vividly Agnes Moorehead brought the character of Mrs. Canby to life.  Actually, all of the characters here are just so incredibly alive in this production.  If I were to try and turn anyone on to old time radio drama, this would be the thing to have them listen to.  The visualizations here are remarkable.  The struggle towards the stairs is truly disturbing, as the listener really can't be certain that Mrs. Canby won't be killed.  Such a likeable protagonist -- you just can't bear the thought of such a horrible end for her.  Bravo to this episode and Agnes Moorehead.
