Pamela Barnes is a professor in psychology who specializes in speech and sound is at Grace University. Kent, her graduate assistant, finds Dr. Charlotte Clark dead in the computer lab, strangled by a cord. Though Clark brought in lots of grant money to the university, she was not popular with the others in the department but Barnes wants to make sure her murderer is found.
Dr. Barnes had heard Clark arguing with the department head Mitchell Marks before the murder and Clark placed a mysterious photo of a former student in Marks mail slot the day she was murdered. The woman arrives and leaves crying. Barnes cannot imagine Marks murdered Clark but thinks it has to be someone in the psychology department. The police are not working as quickly as she would like so she starts investigating.
When the computer lab is again opened, Pamela goes back in to see if she can find something the police may have missed. She wonders if Clark had turned on the sound toggle while she was working at the computer. She checks the main computer and realizes the sounds of the murder had been recorded probably accidentally pushed by Clark in the midst of the struggle. Pamela listens to it and makes a copy. When later than evening Pam tells her husband, Rocky about it he is concerned and tells her to leave the investigation to the police.
Pamela does take the disc to the police but keeps a copy and with her persistence records sounds to find out what is making that non-human clicking sound in the recording that she cannot identify. This leads to a confrontation and the murderer is uncovered.
This book covers the fascinating inner workings of a university dealing with tenure issues, cutbacks, grant money and strong personalities. Rockwell has written interesting characters and I want to read more books about Professor Pamela Barnes.
