A Function of Murder

Dr. Sophie Knowles is a math professor with a knack for creating complex puzzles that delight her students. But now, at the close of the academic year, she must solve a crime that doesn’t quite add up…

At the math department’s graduation party, Sophie hears heated arguments coming from the graduates about Mayor Graves, the commencement speaker. Not the mayor’s biggest fan, Sophie is happy to escape the drama with an after-hours campus stroll accompanied by her helicopter-piloting boyfriend, Bruce Granville. However, their date is interrupted by the mayor himself—with a knife in his back.

As it turns out, the knife is actually a Henley College letter opener—something that is gifted to every member of the graduating class. Sophie is led to a complicated puzzle of scandal and corruption, and it seems that Mayor Graves is at the apex of it all. When Sophie finds out that the mayor was seeking her help on the day he was murdered, she must use her top-notch logic to crack the puzzle and catch the killer running free on campus…
