The world is a foul sty

After watching 78/52 -documentary I felt somewhat compelled to watch an Alfred Hitchcock feature. Not Psycho because it's pretty well forged in my memory, so I randomly picked up Shadow of a Doubt (1943), apparently Hitchcock's personal favourite, but I've seen it only once or never before. Absolutely fine looking piece, classic Hitchcock, people suspect an ordinary family man might be a serial killer, the so called Merry-Widow Murderer. A nail-biting thriller.
