Kay Schneider, protagonist of Mapping Charlie, is back in a second tale of murder, friendship, and detection. Not the suspect herself this time, she is drawn into the role of amateur sleuth by a friend of the man whose guilt seems proved beyond doubt by incontrovertible evidence. Kay has certain disadvantages, one of which is often not being able to recognize people, even when she knows them. But her autistic neurology also leads her into investigative paths unexplored by those around her. In this case, one of those paths leads her right into mortal danger.
