In the Dark (PsyCop #6.1)

Halloween is fun...at least, it's supposed to be. Costumes, candy, trick-or-treat, even jaded Victor Bayne can get behind those sorts of antics. Too bad this year's Halloween is a grownup event. Not only must Vic don a suit and endure a disco-obsessed DJ, he has to mingle with friends of Jacob's he would much rather ignore.

Vic thinks he has the party's host all figured out--but as he so often realizes, once he looks beneath the surface, things are seldom what they seem.
