Stray Dog - A toss-up, really. Love 'em both, but neither really stands out as a "mystery" movie. The Spiral Staircase - Gets the vote to avoid a tie. Spellbound - Ditto. Gaslight
Abstain - no GP The Silence of the Lambs Shadow of a Doubt Se7en - blaspheme I know
BTW - I bitched enough already about what films are really not Mystery films before we started voting. As far as I'm concerned if it's in the tourney, it's in & I'm just voting for the film I enjoy more.
