Murder and the theft of an artificial diamond created by the father of Algy’s wife Gwen (Nydia Westman) causes the postponement of the imminent wedding of Captain Hugh Drummond (John Howard) and Phyllis Clavering (Louise Campbell), as Hugh scrambles to figure out what occurred — though the viewer is aware of at least part of the criminous doings and their perpetrators. An odd shift occurs partway through the movie, as a second crooked party emerges. Reginald Denny (as Algy) and E. E. Clive (as Tenny) are on hand to provide their usual support, but top-billed John Barrymore is a disappointment (and this ended up being his last appearance in the series).

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

Movie 450 for 2021.
