The Bestseller, Jenny Knightsby’s debut novel, is impressive, and not only because it is her first attempt at crime fiction. Although, by profession, a full-time NHS hospital doctor based in West London, in this book Knightsby quickly establishes herself as a confident and accomplished part-time author. She writes in fluent, flowing prose, offering authentic-sounding dialogue and pin-sharp observations. Her plot maintains a quick pace and is replete with surprising twists and turns. Best of all, the novel is peopled by all-to-believable characters—flawed but often engaging—harboring their own secrets and lies. It is probable that Kingsby’s years of meeting and treating the public on the wards and observing people at their most vulnerable accounts for the authenticity of the insights into human nature that are such an attractive feature of this novel.
Knightsby has confessed to an interest in psychologists and people working in publishing, and both types appear in The Bestseller. It is the story of couple’s therapist Helena who finds one patient, a beautiful young woman named Belle, particularly challenging. She has never met Julius, Belle’s husband, because Belle is reluctant to admit to him that she has even engaged the services of a therapist. Helena becomes convinced Julius is a coercive individual who engages in the domestic abuser’s tricks of gaslighting and insults (and, on occasion, compliments and presents) to ensure his wife’s compliance and unquestioning obedience to his wishes. What she perceives as Belle’s plight so arouses Helen’s fascination and indignation, coupled with fear that her patient is in danger, that she breaks the therapist’s cardinal rule of confidentiality, relating details of the case to her best friend Tala, an unsuccessful novelist. Helena’s and Tala’s relationship goes back to university days when, with Dylan—who later becomes Helena’s husband—they were best friends and roommates. In the second timeframe, there is a palpable tension between Dylan and Tala that Helena is at a loss to explain.
In a nod to recent trends in crime fiction, The Bestseller is told in two timelines—the period when the three friends were students and the present, when they are adults in their thirties—and through two perspectives: those of Tala and Helena. Knightsby manipulates this technique, like the best of crime fiction writers, to add nuance and subtlety to her story.
Tala’s publication of a book called Your Enemies Closer propels the action of Knightsby’s addictive thriller. After stealing a proof copy of the book, Helena is horrified to find it seems to be based on what she has confided to her friend about Belle and Julius’s relationship. To her dismay, Tala’s book becomes wildly popular: a ‘bestseller’. Helena is terrified that her disclosure of private details of a patient’s therapy might destroy her career but, even more, fears that Belle and, possibly, even she and her husband might be in danger from a Julius infuriated by the public exposure of his darkest secrets.
This
is a book to savour and enjoy while also one that sets the pulse racing. Highly
recommended.
