Ada Madison - The Square Root of Murder

The unfamiliar feeling of vulnerability unsettled me. I crawled into bed, then crawled out and wedged a chair under the bedroom doorknob. I climbed under my crisp lavender sheet again, and climbed out again to make sure the door between the kitchen and the garage was locked, something I never did unless I was leaving town for a few days.

Reading in bed was one of my favorite pastimes, but tonight I couldn’t concentrate. I opened the drawer in my night table and took out a clipboard with a half-finished crossword. The puzzle was due to my editor in a few days and I hadn’t looked at it at all yesterday or today.

The sad part: I’d been working on a chemistry-related crossword, with Keith’s help. The overall shape of the puzzle was a beaker. Some clues were simple; for “tongs” the clue was “they come in a pair and hold hot things.” I’d asked Keith if he’d contribute a few difficult ones. Not too hard, though, since the puzzle was destined for a kids’ word games book. He’d given me several, starting with “crucible,” for which the clue was “porcelain container for reactions.”

“These are perfect for middle-schoolers,” I’d told Keith. “I didn’t know you had experience with preteens.”

He’d shrugged and said, “I used to be one.”

I doubted it, but then I never would have guessed that Keith was seeing someone. Unless he’d made up a girl to keep his old cousin quiet. I wondered who she was, if she was real. I couldn’t think of a Bonnie on the faculty. I counted three faculty members who could pass for Annie in one form or another-all of them were married, happily from all outward appearances.

Was Annie or Bonnie a student? I hoped not. Elteen had said she was young, but I couldn’t take her literally. Keith might have referred to her as simply his own age. My very last thought was that the “girl” was not part of Henley College. I could hear Ariana saying, “I told you so” about my narrow view of the world.

I cast aside the puzzle that reminded me too much of Keith. Maybe some other year I’d be able to return to it. For now, I’d have to come up with a different theme. I’d already done one shaped like a helicopter with words and clues from aviation history, and I’d covered many other modes of transportation as well.

I attached a clean puzzle grid to the clipboard and tapped the blank squares. Usually I could count on a last-minute inspiration, but tonight I wasn’t sure. Not even the lingering aroma of Ariana’s tea concoction was enough to inspire me.

When the phone rang, my body twitched and the clipboard went one way and my pencil the other. At one thirty in the morning, I dreaded picking up the phone to hear a dial tone. Or worse, a threat. Or news of a second murder. The negative possibilities were endless.

I checked the caller ID. Rachel’s cell phone number. I was almost happy to see it.

“Hi, Dr. Knowles. I know it’s late and I shouldn’t be calling. But I can’t sleep in this bed.”

“Where are you?” Please don’t say jail.

“I’m home in my own room, but it feels weird not to be in the dorm.”

“I forgot some of you were sent home.”

“They closed my dorm. Everyone who couldn’t get home is in Paul Revere with, like, maximum security. I don’t want to be here with my mother still freaking out, but I don’t know why anyone would want to stay at the dorm either.”

I thought of three girls who were very happy to be there, close to what they perceived as “the action.”

“I’m sure everything’s secure on campus.”

“Are you worried something will happen to you, Dr. Knowles? I mean what if some serial killer wants all the Franklin Hall teachers dead?”

Nice going, my friend. “I think you’re overreacting, Rachel.”

“Like, how can you overreact to murder?”

Good question. Until my garage was broken into, I hadn’t seriously considered myself in any danger at home. Keith’s murder had been no threat to me and had not invaded my personal space. At the front of my mind was what if the box thief didn’t get what he wanted and was planning a middle-of-the-night return visit? Or even another middle-of-the-day visit. Hadn’t Keith been killed between noon and just before two, when Rachel found him, in extremely sunny daylight hours, in his own office?

Until someone got to the bottom of this, no one was safe at any hour. I might as well do my share.

“Rachel, did you tell me you did not leave the cake and soda in Dr. Appleton’s office on Friday?”

“I did not. I put them on the floor, outside the door, so it would look like I knocked but the door was locked and I couldn’t get in.” Rachel sounded as though she were speaking to a child who didn’t get it the first time she told me, and rightly so. “That was my big lie, remember, telling the police that I never got in?”

“Are you sure? You wouldn’t lie to me now, would you?”

“No way! You’re scaring me, Dr. Knowles. Why are you asking me this?”

“I’m just trying to review everything, Rachel. And I have one more question. It’s about your draft thesis. Do you have a copy?”

“I have so many copies I can’t count them.”

I knew how that went. Draft after draft and hardly being able to tell which version was which. “How about the ones on those yellow sheets. Do you have more than one copy of those, too?”

“Like, a gazillion. I only use the white paper when I’m ready to show something to Dr. Appleton.”

“So, Dr. Appleton would see only white copies?”

“Yeah, he hated those yellow sheets. ‘If it’s not worth more than cheap paper, something’s wrong with it and I don’t want to see it,’ he’d say.” Rachel had worked her voice into a reasonable facsimile of a male’s.

“Does anyone else have copies?”

“Yeah, we all pass them around to whoever will review them. Not you, because you always say all you know is math, though I know that’s not true. But Dr. Bartholomew would read early versions, and Dr. Emerson, just for, you know format and stuff.”

Fran, my own department chair, read yellow research papers. That meant I couldn’t hide behind the cloak of mathematics any longer.

“So, lots of people had copies-”

“Oh, my God. Dr. Knowles,” Rachel interrupted. “You asked me before if I saw any yellow sheets in Dr. Appleton’s office. Was my thesis in there with him? Like on him or something? Oh, my God, is that it?”

“Calm down, Rachel.”

“Oh, my God.”

I wished there were something I could do about her fever pitch, but we were miles apart.

“Rachel, I’m working on this. I didn’t mean to upset you. I just want to be sure I have all the facts straight.”

“But I didn’t see any yellow pages when I was in there. I swear.”

“Then there’s nothing for you to worry about.”

That last statement nearly choked me. Unless Rachel had hired a real detective and wasn’t counting on me, worry should be her middle name.

Shriek. Bark. Shriek. Bark. Shriek. Bark.

Not quite the Bat Phone, but the deafening noise woke me up.

After all of four hours sleep, the loudest noise ever in my home brought me straight up in bed. The most raucous party in Ben Franklin Hall couldn’t compare on the decibel level.

I had no idea what to do. Punch in the alarm code? Anyone who knew me could figure out the code: 0-1-1-2-3-5, the first six numbers of the Fibonacci sequence. The keypad was near my headboard. I held my fingers over it, about to hit the zero and the rest of the series that would stop the roar. But wouldn’t that defeat the purpose of having the alarm monitored? I should let it keep blaring and wait for the call from SoMass Alarm Company. I should stay in my bedroom until the cavalry arrived.
