Me too, I spent a month in hospital last year and the fact that 4 different channels showed Murder She Wrote at different times during the day definitely helped get me through it.
This was one of the episodes I remember more clearly and I remember it was pretty good although it's fair to say I was on a lot of drugs so my review is probably not entirely trustworthy.
Did you see the one where she stumbles upon the murder of the very last resident of cabot cove, and she is forced into the realization that she is in fact the most prolific serial killer in history.
