From amazon dot com: *Miss Dorothea Balfour was nearer seventy than sixty, but there was something childlike about her . . . She felt rather like a child, a lost, bewildered child, and she was doing what Belle had always objected to so strongly: staring out of the window at 'those rather odd persons next-door' . . .* Shy, uncertain Miss Balfour is still finding her way after the sudden death of her domineering sister Belle, who-following a failed marriage many years ago-had returned home and made a career of brow-beating her meeker sibling (her memorable final words were 'Don't be a fool Dottie'). But Dorothea soon begins exploring her newfound freedom, observing and then becoming happily enmeshed in the doings of her neighbours, the widowed Mrs. Lenox and her five unusual and charming children, with whom Belle had always forbidden contact. Domestic challenges, romantic difficulties, and efforts to aid a painter's abandoned family-all are facilitated by Dorothea's calm intelligence. And before long she has drama of her own, from her spontaneous rescue of an endangered child to her encounter with Belle's long-lost husband, from whom she learns some surprising secrets.

In a striking Victorian London building, newcomer Kate Ashenberry encounters charming, eccentric neighbors—yet some hide darker secrets. As residents vanish in locked apartments, Kate must decide who is safe and who is the killer.
