Dominating the fashionable London street is a striking Victorian building. Inside its gloomy hallways newcomer Kate Ashenberry will meet her neighbors, many charming, many eccentric, and some more than a bit mysterious. But one of these neighbors is not who he or she seems. Residents of the building are dying in their apartments behind doors securely locked from the inside, each victim more horribly than the last. Kate is starting to lose new friends, her home feels more and more like a deadly trap, and she wonders who will be next . . . as, unknown to her, across the courtyard, a lone face watches her rear window.
