Late that night, he is awakened by urgent knocking at his door and finds his father on the porch, agitated and speaking incoherently. Dwayne initially attributes his father's behavior to a severe delusion. However, his father claims to be having visions about Dwayne's sister, Gina, and insists he knows things he shouldn't be able to know. He seeks Dwayne's assistance in setting things right, whether or not Dwayne cooperates. Delusion is the eighth book in the Dwayne Morrow Mystery series.
