The Gist: A young woman adores her dapper uncle and lives for his occasional visits. His latest, however, is accompanied by some odd behaviors and the presence of a couple of investigators looking for the Merry Widow Murderer, a rich widows' serial killer. As her doubts about who her uncle might really be start to grow, so does the danger to her life and that of her family.
Alfred Hitchcock's Shadow of a Doubt is a quite unsettling thriller. I think that the family ties between the main suspect and his next possible victim add to that feeling.
Teresa Wright and Joseph Cotten are perfectly cast in the lead roles.
The Bottom Line: This is a great thriller, primarily because the relationship of the two leads is such that the stakes of the usual game of cat and mouse between victim and perpetrator are upped considerably.
