This short story was the inspiration for the full-length novel, Bound By Suggestion and is a great introduction to the Jeff Resnick Mystery series.
Jeff Resnick, a former insurance investigator with newly awakened--and limited--psychic abilities, has no expectations when investigating the disappearance of a four-year-old boy, until he confronts the mind responsible. It's his first first consultation, which becomes a shattering experience for all involved.
