“I got a text.” Diesel’s tone had gone wary, as if he sensed her panic. “He didn’t have any records of her in his home office, so he’s going in to his office at the university to check, but he’s got some fundraiser or other to attend first. He’ll get to us as soon as he can.”

“All right, then. Can I look at the list?”

Diesel rummaged in his laptop case and brought out a stack of papers, neatly stapled in the corner. “I used your printer last night to make a hard copy. Hope you don’t mind.”

“No, of course not.” She scanned the list of businesses compiled into a tabular format from the state government’s database. Eighty business entities took up four pages and were more words than her brain could process at the moment.

Falling back on what worked for her, she drew a spiral notebook and a pen from one of the kitchen drawers.

“What are you doing?” Diesel asked in confusion.

“I’m going to write them all out.”

“Longhand? With paper? And a pen?”

She had to laugh at his horrified tone. “Yes. The act of writing helps one’s brain dissect and retain information. I started doing this in med school. It was the only way I got through HGA with an A.”

He continued to watch as she started copying out each business name, still apparently disbelieving that she’d actually write with a pen. “What’s HGA?”

“Human Gross Anatomy. Oh.” Something clicked in her brain and she ran her finger down the printed table until she found the entry she was looking for. “Aminus HGA.” She pronounced it AH-minnus, just as she’d heard in her mind every time she’d read through the list. “But it’s not AH-minnus. It’s A-minus. Like, the grade. If all of these business names refer to one person—LJM—then she got an A-minus in Human Gross Anatomy during her first year of med school at UC.”

He blinked. “You’re right. Does Jeremy teach HGA?”

“No, but he’ll know the prof who does. He doesn’t have to check all med students in the files. He can narrow it down to who got an A-minus in Human Gross Anatomy in the years that LJM went to UC. Based on . . .” She ran her finger down the list of companies. “Here. ‘Scioto Associates.’ I took that to mean that she lived at Scioto Hall when it reopened, while she was an undergrad. That had to have been 2016 or later because the dorm was closed for renovations before that.”

Diesel nodded thoughtfully. “When do med students take HGA?”

“We took it the first semester of our first year—that was the fall semester.”
