Hitchcock's Spellbound--Little help?

Last night, Spellbound was on TCM right when I got home from work. I decided to sit down and watch it whilst eating dinner, which then turned into laying down and watching it, which then turned into me falling asleep with about 45 minutes left to go.

And of course, the IMDb offers no clue as to how the movie ends.

So, can anybody help me? What happens after Constance takes the impostor to see her old professor? I got as far as Gregory Peck going downstairs with the straight razor and then drinking the drugged milk. Did he kill the real Edwardes? This is going to bug me until I know, and I won’t be able to get to the video store till at least the weekend (and since Blockbuster is my only option, there’s certainly no guarantee that they’ll even have it). I’ve got enough crap to obsess about without adding this to the list. :smiley:

“Dr. Edwards” (Gregory Peck) not only isn’t Dr. Edwards, but he’s not the killer, either.

Thank you, that’s exactly what I needed! I can go on with my life now. :slight_smile:
