“La Grande? As in La Grande Fromage? This isn’t a cartoon.” Gamache took a long breath and tried to control his frustration. On the speakers they could hear that Morin had moved on to a monologue on heirloom tomatoes.

“This is what I think, sir,” said Gamache. “The kidnapping wasn’t done by a frightened backwoods farmer with a marijuana crop. This was planned all along—”

“Yes, you’ve mentioned that before. There’s no evidence.”

“This is evidence.” With a mighty effort Gamache stopped himself from shouting, instead lowering his voice to a growl. “The farmer has not left Morin alone as he said he would. In fact, not only is Morin clearly not alone, there’re at least two, maybe three others with him.”

“So, what? You think he’s being held at the dam?”

“I did at first, but there’re no turbine sounds in the background.”

“Then what’s your theory, Chief Inspector?”

“I think they’re planning to blow the dam and they kidnapped Agent Morin to keep us occupied elsewhere.”

Chief Superintendent Francoeur stared at Gamache. It was a scenario the Sûreté had practiced for, had protocols for. Dreaded. A threat against this mighty dam.

“You’re delusional. Based on what? Two words barely heard far in the background. It might even be crossed wires. You think that in what”—Francoeur turned to look at the clock—“six hours someone’s going to destroy the La Grande dam? And yet, they’re not even there? They’re sitting with your young agent somewhere else?”

“It’s misdirection. They wa—”

“Enough,” snapped Chief Superintendent Francoeur. “If it’s misdirection it’s one you’ve fallen for. They want you to hare off after a ridiculous clue. I thought you were smarter than that. And who are this mysterious ‘they’ anyway? Who’d want to destroy the dam? No, it’s absurd.”

“For God’s sake, Francoeur,” said Gamache, his voice low and hoarse with fatigue, “suppose I’m right?”

That stopped the Chief Superintendent as he made for the door. He turned and stared at Chief Inspector Gamache. In the long silence between the men they heard a small lecture on cow versus horse compost.

“I need more evidence.”

“Agent Lacoste is trying to collect it.”

“Where is she?”

Chief Inspector Gamache glanced quickly at Inspector Beauvoir. They’d dispatched Agent Lacoste two hours ago. To a remote Cree community. To the settlements closest to the great dam. Most affected by it going up. And most affected were it to suddenly, catastrophically, come down. There she’d been told to visit an elderly Cree woman Gamache had met years earlier. On a bench. Outside the Château Frontenac.

They’d hoped to have her evidence by now. To convince Chief Superintendent Francoeur to stop his high-tech search and lower his sights. To change course. To stop looking at the present and look to the past.

But so far, nothing from Agent Lacoste.

“I’m begging you, sir,” said Gamache. “Just put a few people on it. Quietly alert security at the dam. See what the other forces might have.”

“And look like a fool?”

“Look like a thorough commander.”

Chief Superintendent Francoeur glared at Gamache. “Fine. I’ll do that much.”

He left and Gamache saw him speaking with his own second in command. While he suspected Francoeur of many things, the murder of tens of thousands of Québécois wasn’t among them.

He slipped the headphones back on and rejoined Agent Morin, describing an argument he and his sister once had that resulted in fresh peas being thrown. His voice was once again slow, exhausted.

Gamache picked up the conversation, telling Morin about arguments between his own children, Daniel and Annie, when they were young. How Daniel was the more sensitive, more measured of the two. How Annie, young and bright, could always best her brother. And about the competition between them that had settled, with time, into a deep affection.

But as he spoke he knew two things.

In just under six hours, at 11:18, the La Grande Hydro Electric Dam would be blown up. And Agent Paul Morin would be executed. And Chief Inspector Gamache knew something else. If it was possible to stop only one of those acts, he knew which it would have to be.

“How’s your friend?”

“Friend?” Gamache turned to see Elizabeth bringing a few books into the library and placing them on the “returns” cart.
