Ben Hart is a high school chemistry teacher who thought his biggest problems were test scores and lunch room politics. That was before he lost his job, discovered his colleague murdered, and found himself with a new assignment—catch the killer. Now, as he navigates Diamond Alley's backstreets, his questions are no longer multiple choice: Who can he trust? Will he ever get back to a simple life of worksheets and lab reports? And will he uncover the truth before the killer slips away?
