The scallops were large and succulent and grilled golden brown. They lay on a bed of grains and fresh herbs and roasted pine nuts and goat cheese next to a warm grilled apple. He was about to ask about the pear but was distracted by the bacon club sandwich with thin, seasoned fries put before the professor.

He is smart, thought Beauvoir.

“Can I tempt you?” Rosenblatt asked, pushing his plate a millimeter closer to Jean-Guy.

“Non, merci,” said Jean-Guy, taking a fry.

The professor smiled, but then it faded.

“Who’re they?”

Beauvoir followed Rosenblatt’s scowl and saw Isabelle Lacoste standing in the doorway of the bistro with Sean Delorme and Mary Fraser.

Across the room, Mary Fraser turned to Lacoste. “Is that him?”

“Professor Rosenblatt, oui,” said Lacoste. “Would you like an introduction?”

Isabelle pretended not to hear the urgent whispers of Non, merci behind her as she wove between the tables.

“They’re coming this way,” said Rosenblatt in an urgent whisper. Beauvoir half expected him to bark, “Quick, hide.”

“There you are,” said Isabelle, as though seeing Beauvoir was a surprise and not part of the plan. “We were just coming in for a late lunch too. I don’t believe you’ve met. Professor Michael Rosenblatt, may I present Mary Fraser and Sean Delorme. They’ve just arrived from Ottawa. They’re also interested in what we found.”

Rosenblatt had once again struggled to his feet, though with far less gusto than for Ruth Zardo. He didn’t exactly curl his lip at the newcomers, he was far too courtly for that. But it was close.

“We haven’t met,” he said. “But I believe we’ve corresponded.”

“Yes” was all Delorme said, while Mary Fraser remained silent, though she did shake the professor’s hand. More, Lacoste felt, out of habit than desire.

Lacoste looked around and spotted a table in the corner, a distance from Beauvoir and the professor.

“I think that one’s free,” she said, and watched as the CSIS agents practically climbed over the other tables to get to it.

Chief Inspector Lacoste had asked Olivier not to mention that she’d called ahead and reserved it.

“They work for CSIS,” said the professor, turning his back on them. “But of course, you know that. I think it would be a stretch to call them intelligence agents.”

“Then what are they?” asked Beauvoir.

“File clerks,” said Rosenblatt.

“How do you know them? And how come they know you?”

“I’ve petitioned the government for the files on Gerald Bull and Project Babylon for years. I was planning to write a major paper on him to mark the twentieth anniversary of his assassination. Those two are in the department that keeps the dossier on Dr. Bull, but they won’t release the information.”

“Why not?”

“That’s a good question, Inspector.”

He glanced behind him, and saw Mary Fraser swiftly drop her eyes. Then Rosenblatt returned his attention to Beauvoir.
