Claustrophobia is the taut, compelling story of a young Perth wife who sets about to protect her husband by stalking his ex-lover, but unexpectedly falls into a passionate affair and a world of lies. In a novel that possesses the dark wit, psychological insight and narrative momentum of a Patricia Highsmith, Tracy Ryan captures the disturbing elements that sometimes lurk beneath the surface of a marriage. The realities of obsessive attachment and social isolation are explored through a deft and thought-provoking look at a complex personality and a plot that twists its page-turning way into our psyche.
