This movie is a solid Hitchcock thriller, without going above and beyond. It feels very similar to Hitchcock’s other early work, specifically The 39 Steps and Secret Agent, but done a bit better here. Peter Lorre steals the show as always but there’s a good, thrilling narrative to hold up this film as well.

Closest comparison: It’s like The Lady Vanishes by way of The 39 Steps.

Setting: Espionage
Plot: Detective
Tone: Noir
