“Just tell me what you see.”

He heard vague sounds as she put the phone down and did as he’d asked. Then she was back.

“Norman,” she read.

“Look closer.”

“I’m sorry, Armand. It still says Norman. Just a moment.”

He heard more sounds, then silence. Then footsteps and a crackle as the phone was picked up.

“I got my device. Hold on, I’m bringing up the camera and the photographs. I can zoom in.”

He waited.

“Oh.” Was all he heard. And all he needed to hear.

“What did you want to tell me?” he asked.

It took Reine-Marie a moment to tear her eyes, and her mind, away from what she’d just seen.

She lowered the device, dropping the madman to her lap.

“Professor Norman taught art theory at the college,” she said. “But according to Professor Massey, he didn’t teach the traditional theories about perspective and aesthetics and the nature of art. He taught his own theories.”

“Yes,” said Gamache. “About the place of a muse in an artist’s life.”

“But Professor Norman wasn’t advising the students to get a muse,” she said. “He was teaching them about the tenth muse.”

Armand drew his brows together, trying to remember.

“The tenth muse? I thought there were just the nine sisters.”

“There’s a theory that a tenth muse existed,” said Reine-Marie. “That’s the theory Professor Norman was teaching. Armand, none of the original muses represented painting or sculpture.”

“But they must have,” he said.

She shook her head, even though he couldn’t see her. “No. Poetry, dance, history even. The word ‘museum’ comes from ‘muse.’ ‘Music’ and even ‘amuse’ come from the word ‘muse.’ But there was no muse for art itself.”

“Hardly seems possible,” he said, though he believed her.

“Professor Massey admitted he couldn’t remember the details, if he ever knew them, but he did know that Professor Norman’s theory was that there was in fact a muse for art. The tenth muse. And to be a successful artist you needed to find her.”

“Are you saying that Norman believed this tenth muse actually exists? Is living somewhere?”

“I’m not saying it. Professor Massey wasn’t even saying it. But Sébastien Norman was apparently teaching it to his students. But there’s something else. Something Ruth said.”

“I’m ready,” he said, and sounded so stoic Reine-Marie smiled.

“She quoted Degas saying the muses work all day and get together to dance all night.”

“Nice image.”

“Ruth wondered what it would be like to be standing in the forest, watching. Eternally excluded.”

Another image sprang to mind. Of a shadowy figure. Among the trees. Longing to belong.

Instead she was rejected.

And eventually that pain turned to bitterness, and the bitterness turned to anger, and the anger became rage.

Until that rage became madness.

And the madness became a portrait.
