Overall, this entry in the Bulldog Drummond series is just an average B-feature, but it does have some good moments. This was the first feature in the series to star John Howard as Drummond, and it also has the usual supporting characters, with E.E. Clive and Reginald Denny as Drummond's sidekicks, Louise Campbell as Phyllis, and John Barrymore as Colonel Neilson. Howard, Clive, and Denny have some good lighter moments together during the course of events, and Barrymore, as you would expect, makes very good use of his opportunities, leaving you wishing there had been more scenes involving his character.
The story idea is interesting if lightweight, with villains played by J. Carrol Naish and Helen Freeman using a series of riddles and puzzles, along with a kidnapping, in their attempts to lure Drummond into a trap. The series of puzzles gets a bit far-fetched, but it does hold your interest, and perhaps with a little more careful writing and editing it could have made a pretty good movie.
Barrymore's series of disguises and other tactics is probably the most entertaining part of it all, and these also help to keep the tone light. Otherwise, there's nothing particularly impressive, but it has just enough to be worth seeing for those who enjoy the genre.
