Gamache was silent for a moment, then opened his mouth. But there were no words. Certainly none of the reassuring words she was hoping for. The candlelit words. And to Reine-Marie’s horror, he simply closed his mouth and looked at her.

“Do you think the killer found the plans?” she asked quietly.

“I don’t know,” said Gamache. “Mary Fraser accused me of not understanding how dangerous the world of arms dealers is. And she’s right. I don’t think anything we’ve faced compares to it. The scale of death they deal in is almost beyond comprehension. They create and feed wars, they encourage genocide. For profit. And what a profit. The money must be in the billions. Lives are worthless, incidental.”

He spoke almost matter-of-factly, which only added to the horror of what he was saying.

“I think we have to assume the worst,” said Jean-Guy. “That the plans have been found.”

The dinner broke up shortly after that. There didn’t seem much else to say. They made arrangements for Adam Cohen to take Beauvoir’s room at the B and B while Jean-Guy moved into the Gamaches’ home. The young man seemed relieved not to have to drive back to the city.

After Lacoste and Cohen had gone and the dishes were done, Armand and Henri went for a walk.

“Mind if I join you?” Jean-Guy asked.

The three of them walked in companionable silence around and around the village green. It was a clear, cold night and they could see their breath. The sky was filled with stars, and moon shadows from the three huge pines stretched across the grass and landed at the bistro.

They could see Professor Rosenblatt sitting alone at a table. Gamache paused and thought. And knew it was time.

“Chilly night,” he said to Jean-Guy. “I feel like something to warm me up.”

“I was thinking the same thing, patron.”

A minute later they were standing over the professor’s table.

“Bonsoir,” said Armand.

“Hello,” said the professor, looking up and smiling.

Armand took the photograph from his pocket and placed it on the bistro table, sliding it slowly forward, toward Michael Rosenblatt.

“I’d like an answer to my question now, s’il vous plaît,” said Gamache. “Did Gerald Bull design the Supergun? Or did someone else? Someone smarter?”

He watched as the smile flattened. Flatlined. Died on Rosenblatt’s face.

“Last call,” said Olivier from behind the bar.

There were two other occupants of the bistro, young lovers on a date, holding hands across the table. Gamache wasn’t worried about them. They clearly were in their own world. One that, thankfully, did not include genocide, and warheads, and dark things hidden in deep forests. Gamache wanted to make sure the two worlds did not meet.

“Monsieur?” Gamache nodded toward Rosenblatt’s cognac.

“Oh, I think not.”

The elderly scientist was slurring slightly, and now blood rushed, in a flush, to his face.
