This British action movie is a stark departure from the earlier Ronald Colman film, this one from British International Pictures and director Walter Summers. Ralph Richardson steps into the title role as the former military man turned private detective. He's now settled down and married to Phyllis (Ann Todd), but when an international cabal of arms dealers led by Drummond's nemesis Carl Peterson (Francis L. Sullivan) uses murder to try and thwart peace talks, thus causing another world war from which they can profit, Drummond organizes his fellow military comrades into a secret group known as the "Black Clan" to stop Peterson's gang.
Colman's turn as the title character was a suave adventure done on a lark, with as much comedy as suspense. This outing is more akin to a Saturday morning serial, with multiple cliffhanger moments, nefarious villains straight from a comic strip, and the odd sight of Drummond and his Black Clan allies dressed in matching black outfits and leather aviator caps. Richardson seems like an odd casting choice, but he's good with the verbal putdowns and he's surprisingly energetic during his many fisticuffs scenes. The following year he would appear in the next Drummond film, Alias Bulldog Drummond aka Bulldog Jack, but not in the title role. Also, even later entries in the Bulldog Drummond series would feature Drummond as unmarried with some mystery getting in the way of Drumond's nuptuals to Phyllis.
