When a guest meets his doom via poison during a medical convention at a big hotel, mystery novelist Roger Blackwood (Edmund Lowe) and hotel detective Andy McCabe (Victor McLaglen) extend their good-natured rivalry to competing to find the guilty party — and there is no shortage of suspects. Lowe and McLaglen, who teamed in 10 movies of various kinds, work well together, and their interactions carry a good part of the interest for the movie. Unfortunately, the version I saw ended extremely abruptly, suggesting that part of the film was missing and making the conclusion a bit unsatisfying, although it did suffice to give a solution to the mystery.

  Mildly recommended. Otto judiciously thinks this movie is OK, but not great.

Movie 52 for 2021.
