Growing up, Kate Priddy was always a bit neurotic, experiencing momentary bouts of anxiety that exploded into full blown panic attacks after an ex-boyfriend kidnapped her and nearly ended her life. When Corbin Dell, a distant cousin in Boston, suggests the two temporarily swap apartments, Kate, an art student in London, agrees, hoping that time away in a new place will help her overcome the recent wreckage of her life.
But soon after her arrival at Corbinβs grand apartment on Beacon Hill, Kate makes a shocking discovery: his next-door neighbor, a young woman named Audrey Marshall, has been murdered. When the police question her about Corbin, a shaken Kate has few answers, and many questions of her ownβ curiosity that intensifies when she meets Alan Cherney, a handsome, quiet tenant who lives across the courtyard, in the apartment facing Audreyβs. Alan saw Corbin surreptitiously come and go from Audreyβs place, yet heβs denied knowing her. Then, Kate runs into a tearful man claiming to be the dead womanβs old boyfriend, who insists Corbin did the deed the night that he left for London.
When she reaches out to her cousin, he proclaims his innocence and calms her nerves . . . until she comes across disturbing objects hidden in the apartmentβand accidently learns that Corbin is not where he says he is. Could Corbin be a killer? And what about Alan? Kate finds herself drawn to this appealing man who seems so sincere, yet she isnβt sure. Jetlagged and emotionally unstable, her imagination full of dark images caused by the terror of her past, Kate can barely trust herself . . . So how could she take the chance on a stranger sheβs just met?
Yet the danger Kate imagines isnβt nearly as twisted and deadly as whatβs about to happen. When her every fear becomes very real.
