This is one of Maugham's least-read works, judging from its absence in most bookstores and libraries. Of Human Bondage, Cakes and Ale, The Moon and Sixpence are usually fairly easy to locate on most shelves. You must do a little digging to find this one, but it will reward your efforts.
At the center of the book is Oliver Haddo, who, as you can tell from the other reviews here, is based entirely and without much thought of disguise upon Aleister Crowley, the London necromancer. The plot is indeed pure melodrama, the virginal fiance drawn irresistibly towards her doom by dark forces against which there appears to be no defense. Think of Bram Stoker, or Coppola if you haven't read the novel. Will our hero somehow find a way to overcome the great odds and emerge victorious? Will Haddo succeed in his plan of evil debauchery? Stay tuned for the heady conclusion.
What saves The Magician from sinking into the morass of its conventional and even hackneyed plot is the quality of Maugham's writing. We are aware at all times that we are in the hands of an accomplished writer and artist, who can turn a tired theme into an event of wit and real pathos. At times the scenes are in fact quite chillingly rendered as well. There is real suspense here, as well as some startlingly weird and realistic depictions of the occult. The scene that comes most readily to mind is Haddo's creation of the homonculi, some home-grown little fiends he cooks up in a test-tube. Many of the scenes have a surreal edge to them, but are grounded in enough realistic detail to lend them plausibility at the same time.
I would recommend this book to those who have read and enjoyed Maugham's other works, as well as to anyone who enjoys books about the occult or to fans of horror novels (of which there are legion). It's an easy and fun read and is frightening enough that it just might have you looking over your shoulder the next time you're dining in a London restaurant, double-checking to see if Haddo might not be sitting somewhere across the room. Then again, these days, a lot of women probably hope that he is.
