How to Commit a Murder, Get Trapped by a Flood, and Realize Your New Roommate is the Only Witness
It’s 3:15 AM. My eyes feel like they’ve been rubbed with coarse sandpaper, the cold pizza on my desk is starting to look back at me, and I am currently watching a mysterious, elegant man on a train train predicting exactly when the carriage will shake, while telling a story to a passenger who has absolutely no idea she is already dead.
Welcome, my friends, to the rain-soaked, claustrophobic, and wonderfully cheap world of Lew Landers.
If you’ve never heard of Lew Landers, congratulations: you’ve never dug deep into the bargain-bin of post-war B-movies. For the uninitiated, Landers was a highly prolific director who could shoot a movie in his sleep. His filmmaking method for this psychological noir was a masterclass in low-budget efficiency:
- Slap the name of a massively popular radio show (Inner Sanctum Mysteries) onto your movie to trick audiences into buying tickets, even though your plot has absolutely nothing to do with the radio show.
- Build a story around a torrential flood so you only have to shoot your characters trapped inside a single, dimly lit boarding house.
- Make your main character so incredibly suspicious and dark that he tries to murder a child within the first thirty minutes of the film.
The result? Inner Sanctum (1948).
The “Plot” (If we can even call it that)
A slick, angry fellow named Harold Dunlap gets off a train in a small Pacific Northwest town, gets into a fight with a woman, and stabs her to death with a nail file. He dumps her body back onto the departing train, thinking he’s committed the perfect crime. Too bad for Harold, a young, annoying, freckle-faced kid named Mike sees him do it.
Harold tries to make a run for it, but a massive storm hits and the local river overflows, completely flooding all the roads out of town. He is trapped. A local newspaperman suggests Harold stay at a boarding house until the rain stops. Harold checks in, flirts with the landlady’s attractive niece, Jean, and then gets the shock of his life: the kid who witnessed him at the train station lives in the exact same boarding house. In fact, Harold is forced to share a room with him.
What follows is an hour of Harold trying to figure out how to silence a kid without the kid’s mother, a nosey reporter, and the suspicious niece finding out he’s a cold-blooded killer.
Why You Need to Watch This Tonight
- The Ultimate Awkward Roommate Situation: The tension in this movie doesn’t come from big action scenes; it comes from the pure, hilarious awkwardness of a murderer trying to act casual while sleeping in the same room as the kid who can send him to the electric chair. It is the gold standard of B-movie anxiety.
- The “Seer” Framing Device: The movie has a bizarre but highly effective framing story on a train, where an old man with “second sight” (played by Fritz Leiber Sr.) predicts every bump and flicker of the train cabin before telling the passenger a story. The twist ending of this framing device is actually surprisingly clever and satisfying for a movie that only runs for 62 minutes.
- Pure 1940s Noir Atmosphere: If you like dripping rain, long shadows, fedoras, and morally compromised characters, this movie delivers. The lead actress, Mary Beth Hughes, plays a great noir dame who is highly suspicious of Harold but also kind of wants to run away with him anyway because she is bored of her small-town life.
The Verdict
Is it a masterpiece? No, it’s an average, formulaic B-noir. But at a brisk 62 minutes, it doesn’t waste a single second of your time. It is a gritty, rainy, and thoroughly entertaining time-capsule of post-war cinema that proves you can build a solid thriller with nothing more than a boarding house set, a fake rain machine, and a very dark protagonist.
My Rating: 3 out of 5 nail files used for highly non-manicure purposes.
Wanna watch a killer get trapped by the weather?
Get a hot drink, listen to the rain outside, and search for this obscure 1940s noir on your favorite classic movie channel or public domain platform. Because it has slipped into the public domain, you can watch Harold Dunlap panic in glorious, shadow-heavy black-and-white completely free.
