Did Talbot Mundy intend to pen a sort of Theosophical Bible? I begin to wonder, especially with The Devil's Guard. It is a follow up piece to Om: The Secret of the Ahbor Valley. Unlike the the latter, which followed Cottswold Ommony's temporal and philosophical journey across northern India, The Devil's Guard returns to an action adventure, with Ramsden, Jimgrim, Narayan Singh, and one of Mundy's favorite secondary characters, Chullunder Ghose, the babu. There are some philosophical ingredients, here, but the majority of the novel seems like a sort of Theosophical version of Numbers, where Ramsden, Ghose, and Singh are denied entry into the Promised Land. In each case, it is because of a flaw, as was the case with Moses' sin at the Waters of Maribah. Maybe that is pushing it too much. Still, it is plain that Mundy is bringing his Jimgrim series towards a close with Devil's Guard and the Promised Land of Sham-bha-la now in sight. And the action has moved to involve the core three only, plus the babu. Gone are Ross, King, Ommony, Strange, Leich, and a host of secondary characters that have filled the series.
In keeping with his want to experiment continually, however, Mundy does undertake one interesting detour. Because we know so much of Ramsden, Singh, and Jimgrim by this point, little is left to develop them psychologically, although there is some additional insight gained into Ramsden, here. But the true case of character exploration in Devil's Guard comes with Mundy's portrayal of the babu. His motivations, fears, and loyalty come under examination. Seen against his past action, it is a much more sympathetic view. The shift in Mundy's attitude is reflected in the dialog. No longer is Chullender Ghose's speech so filled with broken English. No longer is it merely comic. Here, Mundy takes him seriously. It is one of the biggest payoffs at the end.
