Mystery Cozy
Dr. Sophie Knowles loves using puzzles to make math fun for students. But when winter seizes Henley College, she must thaw out a cold case to track down a killerβher most difficult puzzle yet . . .
Winter Intersession is in full swing, and campus is buzzing over the concert celebrating the bell towerβs reopening. The building has been shuttered for twenty-five years, and Sophieβs shocked to learn whyβa student leapt from it to her death. But sheβs even more troubled by the secrecy surrounding the case. After Sophie performs some quick calculations, sheβs left with a nagging question: Was it really suicide?
When one of Sophieβs favorite students, a performer in the concert, is brutally beaten and left in a coma, Sophieβs mind kicks into overdrive. The horrific incidents seem too coincidental to be unrelated, but can Sophie put together the pieces from a twenty-five-year-old murder before any other students get hurt?
