Sharp dialog and decent plotting make this another of the better entries in the Bulldog Drummond series. This time, John Howard as Hugh Drummond is entangled in a murder and diamond theft in Switzerland and tracking the heavies back to England. Nice locations, some train and airplane travel, explosions, and a bullwhip vs sword fight make for a nice adventure. Barrymore as Nielson doesn't have much to do, nor do Phyllis or even Algy, but faithful Tenny is on hand, of course (even riding a motorcycle!). For those keeping score, in this one, Drummond starts out in Switzerland about to marry Phyllis, and for once Algy isn't worried about anything.
Also interesting is how this little potboiler was well ahead of its time with the invention of artificial diamonds and corporate conspiracies to suppress rival technology.
