Lives of the Twins is Joyce Carol Oates' one (and apparently only) venture into writing under a pseudonym, Rosamond Smith. It's an interesting little novel with an intriguing pretense - a seemingly insecure, ungrounded woman named Molly Marks falls in love with her psychotherapist, Jonathan McEwan. After months of the affair, they decide to move in together, and on the evening they are first in the apartment, Jonathan casually mentions having an identical twin. He says little else other than that they are not extremely close, and makes only a slight hint that they had a falling out. All of this is much to Molly Marks' (I use her full name purposefully - I will explain) chagrin, which immediately sets the rest of the book's events in fierce motion. Molly Marks - behind Jonathan's back - sets out to find and meet James, his twin brother, who is also a psychotherapist (surprise! maybe not...) and discover what he is like, and what mysterious reasons or reasons pulled them apart. Beyond that, I am afraid I venture into spoiler-land, so I will refrain.
What I will say for any curious reader of this novel is to not be prepared for too much to happen in this book. It can be a quick read, easily, but it's more psychological than eventful. Oates/Smith is clearly exploring the entire theory of identical twins; how much of their identity and what makes them "alike" also makes them standout and be unique. Whenever there is something drastically different between their personalities is wherein the suspense of this book lies, and Oates/Smith is cleverly adept at dropping these little revelations into the reader's laps unexpectedly. Jonathan is younger, seemingly kinder, remote, and quieter. James reveals a cynical, clever, almost sadistic side as the older of the two. Bouncing to and fro, and fretting all the while, between the two is Molly Marks - curiously referred to by her full name throughout a majority of the novel. As Molly becomes, in essence, a patient of both brothers (again, I reveal nothing further), I cannot help but feel that Oates/Smith intended this as a clinical device, keeping her somewhat separate to the observer, all the while being the protagonist. Jonathan and James' characters are the true depth of the story here.
Again, this psychological, almost thriller-type novel can move fast - there are chapters that are only 1-3 sentences long. Oates/Smith leaves much to ponder, especially at the rather surprise ending (which can be either a letdown or just about right, depending upon how the book sits with you as you read it). Supposedly, Oates was disappointed when her ruse as Rosamond Smith was discovered, and never used a pseudonym again. I went into this book knowing that Smith was Oates, and the writing style is undeniably and completely Oates. Those who begin with this novel before any other books by Oates would understandably not draw the parallel too immediately. I would suggest reading other stronger Oates pieces first - Lives of the Twins is okay, and intriguing enough, but nothing too amazing. I would rank it 3.5 stars for the cleverness of the story, but going along with Good Reads star ranking will keep it fixed at 3.
