This novel has an episodic nature due to its origins as a magazine serial, as did the last Sax Rohmer novel I read, BROOD OF THE WITCH QUEEN. I think THE QUEST OF THE SACRED SLIPPER holds together a little better, though, and has enough drive to keep it moving steadily forward even though the seams between the installments show pretty plainly. The book starts out well and then becomes even better part of the way through with the introduction of another character, an American criminal mastermind known as the Stetson Man, who is also trying to get his hands on the slipper. Earl Dexter is a Westerner who wears a Stetson (hence the nickname), and he’s as out of place in England as the Hashishin are, putting poor Cavanaugh in the middle of two colorful enemies who are out to steal the slipper.
All that said, THE QUEST OF THE SACRED SLIPPER is a very entertaining yarn, and Earl Dexter is an interesting enough character that I wish Rohmer had written more about him. I enjoyed this novel quite a bit and I’m sure I’ll be reading more by Rohmer in the relatively near future. By the way, THE QUEST OF THE SACRED SLIPPER is in the public domain and there are free e-book versions in numerous places on the Internet, plus some very reasonably priced and well-done reprint editions.
