"But I didn't do it." "What! Then who the heck did?" The Dark Hour keeps viewers—and detectives—guessing until the final moment. A truly puzzling mystery combined with some juicy performances make this quite a nifty little hour of fun.
Berton Churchill as the retired detective—respectfully requested by his younger counterpart Ray Walker to assist on the case—is wonderfully nimble-minded and yet perhaps suspicious. Irene Ware is earnest and intelligent as the niece of rich old uncles in whose house the mystery develops—but she's obviously hiding something. Hedda Hopper bustles in occasionally with energy and smarts as an aunt who seems to know plenty but isn't saying just what.
Not a fancy movie, but one that's paced just about right: The action certainly moves along quickly, but care is taken to allow us time to notice which characters are thinking a bit more than they're saying. Irene Ware's character, for example, is given an extra moment of screen time here and there—just enough of an extra glance for us in the audience to see quite clearly that she's holding something back. Again, it's not fancy or subtle—but it does show that director Charles Lamont was paying attention.
The dialog is crisp enough; the actors move with energy. Hopper and Churchill, in particular, appear to enjoy themselves immensely in their roles.
My only complaint is that the sound is badly chopped up in the version I saw. Lines are dropped and cut into pieces (including in a couple of key moments!). I can only assume that the print from which this came had been shown about a hundred times and broken and been spliced in about that many places. Oh, well—I can live with that. Otherwise: a top-notch B mystery.
