He checked Evelyn’s desk calendar, saw her appointment with him at the Moosehead and the four fifteen Penny had mentioned, which was with Dr. Ricardo, but nothing else, and began going through the papers on her desk, her phone messages, her drawers. “And inmates? Which ones has she been focusing on lately?”

She frowned as she watched him. He wasn’t being particularly careful to leave things as he’d found them. He was in too big of a hurry. “She’s been frustrated with Mary Harpe, our only female psychopath.”

“The former nurse who murdered those babies.”

“Yes.”

She rounded the desk, pulled open the filing cabinet against the wall and handed him Mary’s file. He’d heard Evelyn talk about Mary. Other than Jasper, she liked Mary less than any other psychopath she’d ever studied. “Is there anything in particular Evelyn has been saying about her?”

“Not really.”

She watched as he leafed through Mary’s file, skimming Evelyn’s handwritten notes on their sessions—mentions of her lack of remorse, her total indifference to the parents of the babies she’d killed as well as the pediatric doctor whose practice she destroyed. He also came across several graphs showing the number of deaths that had occurred in the hospital where she worked before the hospital got rid of her—by laying her off while still giving her a recommendation—and she went to work for the pediatrician.

“Nothing stands out to you as unusual or worrisome?” he pressed. Evelyn often talked about her work when they were relaxing together in the evenings, but he hadn’t heard anything of note lately, certainly nothing that would put him on high alert.

Penny seemed at a loss. “She just told me that some psychopaths are more charming than others and Mary is way down the list.”

Essentially what Evelyn had said to him. “Does Mary dislike Evelyn?”

“She dislikes everyone, but maybe she dislikes Evelyn more than the other doctors. Evelyn sees through her crap from the get-go. The men give her more leeway, more understanding.”

“Does Mary get many letters or visitors? Have any family to speak of?”

“I don’t know. I’ll have to check with Dr. Jones.”

Amarok glanced up. “Why Dr. Jones? Has he been working with her, too?”

“Yes, and they seem to be on friendlier terms.”

When Amarok closed Mary’s file he noticed another file sitting on top of the cabinet, as though Evelyn had recently accessed it. He grabbed it so he could read the name on the tab. “What about this guy—Robert Knox?”

“He’s not a violent offender. He’d be unlikely to harm anyone.”

“But he is a psychopath. A con artist or con man, right?” He’d heard Evelyn mention Knox before, too. Knox had callously bilked several old ladies out of their retirement savings with his investment schemes.

“Yeah. But Evelyn seems to like him okay.”

“Does he have any visitors, mail, that sort of thing?”

“I have no clue. You’ll have to check with the mailroom. Or I can do that for you.…”
