Flemtone

Just finished watching 'Ten Little Indians' and noticed that the 'Whodunnit Break' at the end (when Hugh O'Brian and Shirley Eaton were facing off as the last two survivors - and the infamous minute-long 'Whodunnit Break' was missing. I'm confused - my understanding was that TCM didn't edit their films. This is the first time I've ever noticed an edit (and this channel is on almost 24/7 in our house). Were there multiple versions of this film?
