PASSAGE AT ARMS is the last in the series of the Colonel March stories and it's an easy watch, with Karloff and Roberts slipping into their roles like an old glove. It's a pity that they didn't make more of these stories because they managed to overcome budgetary constraints and were more often than not watchable mystery stories indicative of their era.
This tale is centred around the sport of fencing with a couple of competitors implicated when an apparent suicide turns out to have been murder. Although the story is set in the UK, Eric Pohlmann's French inspector, Goron, turns up to make some of his usual wry comments. Karloff even lifts the sabre himself at one point. There's little of the weird stuff here that made the best episodes of the show ones to watch, but it's a well-paced little thing nonetheless.
