Trust No One

Olivia Blake sells houses. An email comes in from someone wanting to view a property that has been on the books too long, and when she gets there the door is already open, there is a Christmas song playing somewhere in the house, and a man is chained to a chair.

Afterwards a note reaches her, about a night in Norfolk when she and several other teenagers were involved in something that ended badly and was never properly accounted for. The others from that night start reappearing.

Keri Beevis sets it at Christmas and keeps the group small, which means the person doing this is almost certainly one of the few people Olivia would otherwise turn to. Her boyfriend Noah is determined to help her get to the bottom of it. He is also, like everyone else here, carrying something he has not told her.
