But Lenox suspects something far more sinister: murder by a rare and deadly poison. The house where the girl worked is full of suspects and, though Prudence dabbled with the hearts of more than a few men, Lenox is baffled by an elusive lack of motive in the girl's death.When another body turns up during the London season's most fashionable ball, Lenox must untangle a web of loyalties and animosities. Was it jealousy that killed Prudence? Or was it something else entirely, something that Lenox alone can uncover before the killer strikes again -- disturbingly close to home?

    But the road away from Sandling Island seems littered with obstacles. Most pressing of all, her 15-year-old daughter, Charlie, has yet to return from a night out... Minute by minute, Nina's unease builds to worry and then panic. Has Charlie run away? Or has something more sinister happened to her? And why will nobody take her disappearance seriously? As a series of half-buried secrets lead Nina from sickening suspicion to deadly certainty, the question becomes less whether she and her daughter will leave the island for Christmas - and more whether they'll ever leave it again.
