One goes into Zoe Heller's "What Was She Thinking?: Notes on a Scandal," a novel with a blowout of a premise, with some heavy expectations. What you get is a slightly unexpected but nonetheless worthwhile and intriguing reading experience, even if you can't help but wish there had been just a little of the melodrama you had anticipated. Heller's narrative, centered on the scandal surrounding forty-one-year-old Sheba Hart -- who has been caught having a sexual relationship with a sixteen-year-old student at the school where she teaches pottery classes, is remarkably staid and free of soap opera theatrics (even though she does imbue her tale with a dose of humor for levity). Heller focuses less on the aftermath of Sheba getting caught than she does on the year and a half preceding the uproar -- the time period in which Sheba first caught the student's eye, slowly got drawn into the affair, and began to lose control to an obsession over her young lover. Heller is struggling to answer the question that she has posed in the title: what was this otherwise right-thinking woman doing getting involved with a student? She does a passable job hinting at how it happens, but never really overcomes the vagaries of her characters. In the end you have theories but no concrete rulings on the how and why of it. I personally appreciate some of the room left for conjecture, but I can see how others would be left frustrated and put off by the vagueness of it all. At any rate, it is quite interesting to follow Sheba's collision course for disaster. The novel also has an unexpected sub-plot involving Barbara Covett, the spinsterly narrator of the story who is harboring an obsession of her own -- on her friendship with Sheba. Because Barbara is busy narrating Sheba's story -- and remains thoroughly unaware of how odd her obsession is or of just how deep it seems to run -- you are only afforded glimpses of how or why she behaves the way that she does. Barbara is only seen through the prism of her relationship with Sheba, with only hints at her formative years with a poor family and an aggressively religious sister. This would make a great choice for a book club, because I am sure that every reader could take away a slightly different interpretation of this novel that would make for great discussions (or, potentially, arguments). A film adaptation is coming later this year, and I can't wait to see how Cate Blanchett and Judi Dench flesh out their characters, but I think that I will miss the way the novel allows you to come to your own conclusions.
