The Square Root of Murder (Professor Sophie Knowles)

of static electricity. On my phone, I had a photo of one student with her long red hair standing out straight from her head. I thought it best not to show the dean.
    “The physics majors put together a demonstration of one of Tesla’s experiments. It was spectacular, but harmless, really,” I told the dean.
    I spent the next few minutes explaining our custom of monthly parties honoring mathematicians and scientists. I’d been through this description a number of times. Did this dean not listen? Was she too busy being the fashion police? Or did Dean Underwood simply have a short memory for practices she didn’t like?
    I gave it my best, final shot. “There’s more to these gatherings than cake and loud noises. The science and math majors research the scientist or mathematician with the birthday of the month and present reports and demonstrations.” I waited for a response. There was none. “I guess this month’s meeting was especially animated,” I added.
    I hoped for a compliment on what had been my own inspired idea. I could trace it back to my parents, who’d named me after the eighteenth century French mathematician, Sophie Germain. Sophie and I shared a birthday—April first. We celebrated together every year. How could we not share a love of mathematics?
    “Try to keep a measure of decorum, Dr. Knowles,” the dean said finally, sending a loud, agonized breath my way. She stood up and I followed suit.
    I wondered who shared a birthday with Dean Underwood. Someone with no sense of humor, I supposed.
     
     
    On the way to my Ford Fusion, I thought of several brilliant responses I should have made to the dean’s reprimand. For one thing, I wished I’d invited her to the August seventeenth party, for Pierre de Fermat’s birthday. My math majors were preparing a skit about Fermat’s Last Theorem, which he had declared “remarkable,” but never proved. I’d been warned by my students that there was a limerick involved in their interpretation.
    I knew I should have been relieved that I hadn’t crossed the line into sarcasm the dean might recognize. After all, my ranking was at stake. Still, it would have been fun to tell her she didn’t have to bring a present for Fermat. He wouldn’t be showing up.
    I’d also neglected to mention to the dean that the next party wasn’t that far off. Tomorrow, in fact, the four Franklin Hall departments would be celebrating a brand new doctoral degree. Hal Bartholomew, the students’ favorite physics instructor, had completed all the requirements and would graduate at the end of the year from Massachusetts University.
    It was common knowledge that Hal’s thesis had been rejected twice before by MU’s faculty committee. He’d been burdened with an uncooperative crystal to study and had had difficulty acquiring spectral data. He was also balancing his research time with his full teaching load and family life.
    As I understood it, delays in collecting data occurred often to those in experimental physics. And anyone who’d ever been in grad school in any field sympathized with the setbacks on the way to an advanced degree.
    Anyone except Keith Appleton, that is.
    Keith took every opportunity to make a snide remark about Hal’s struggle. I’d never forget his comment when Hal sneezed at Henley’s baccalaureate dinner in June.
    “Stay well, Hal,” Keith had said. “After waiting so long and after all those false starts, you don’t want to miss your graduation ceremony.”
    To his credit, Hal smiled at the remark and ignored the chance to respond in kind. Gil, his wife, found a way to make a point, however: She put her arm around her husband’s shoulders and said, “Hal will be fine. He has me to take care of him.”
    And you, Keith, those in earshot added silently, have no one.
    Cheers for Gillian Bartholomew.
    As I drove home I amused myself by conjuring ways to get even with Keith for not telling me himself that our Tesla party disrupted his . . . what? His quiet time? His life? Keith brought out the worst in me.
    Then I remembered I’d promised to approach him, nicely, on Rachel’s behalf.
    I wished there was a way to banish Keith Appleton from Franklin Hall. And Dean Underwood from the entire Henley campus.

CHAPTER 3
     
    Let it be said: math and science majors know how to party.
    To coincide with Hal’s research field, the physics majors had decorated the lounge with a sepia-colored poster featuring Nobelists in physics for the last fifty
