York Cycle of Mysteries #7
Part of the Dutch House has been converted into flats, inhabited by a diverse but fairly harmonious group of people, and despite Julia's misgivings more or less everyone rallies round at the opening. Even the follow-up from the local antique dealers seems fairly harmless. Then disaster strikes. One of the Dutch House community is found brutally murdered, and a selection of her most valuable antiques is missing.

Detective Robert Southwell is assigned to the case. At first he thinks the murderer must be someone from outside but he changes his mind as he discovers that not all is as it seems in the apparently respectable lives of the flat-dwellers.
