Now he turned and walked toward the old railway station, lit and almost as welcoming as the bistro.

‘Chief,’ Lacoste called as soon as he entered, cold air clinging to him. ‘Am I glad to see you. Where’s the Inspector?’

‘Sick. He thinks Beatrice Mayer put a curse on him.’

‘Wouldn’t be the first woman.’

‘True.’ Gamache laughed. ‘Where’s Agent Nichol?’

‘Gone. Made a few calls then disappeared a couple of hours ago.’ She watched to see if his face reflected how she felt. Nichol had buggered up again. It was as though she had a compulsion to screw up her career and their cases. But Gamache didn’t react.

‘What’ve you got?’

‘A mountain of messages. The coroner called. She says she’ll meet you in Olivier’s Bistro at five thirty. She lives around here, doesn’t she?’

‘In a village called Cleghorn Halt, down the railway line. This is on her way home. Does she have something?’

‘The completed autopsy report. Wants to talk to you about it. Also you have a call from Agent Lemieux in Montreal. He says he sent something to you over the internet. It’s from headquarters. But he also wants a callback. But, before you do…’ She walked back to her desk, Gamache following. ‘I found Eleanor de Poitiers.’

Lacoste sat and clicked her computer. A picture appeared. It was a black and white drawing of a medieval woman on horseback carrying a flag.

‘Go on,’ said Gamache.

‘That’s it. That’s her. Eleanor de Poitiers was Eleanor of Aquitaine. Her.’ She pointed to the screen. Gamache pulled up a chair and sat beside Lacoste, his brows drawn together and his whole body leaning forward, drawn to the screen. He stared, trying to make sense of it.

‘Tell me what you know.’

‘What I know or what I think? Either way, it’s not much. CC de Poitiers listed her mother and father as Eleanor and Henri de Poitiers, of France. In her book,’ Lacoste pointed to the copy on her desk, ‘she describes her childhood of privilege in France. Then there was some sort of financial catastrophe and she was sent away to Canada, to live with distant, unnamed relatives, right?’

Gamache nodded.

‘Well, Eleanor is her.’ Once more Lacoste nodded to the medieval equestrienne, then she clicked again and the screen changed. ‘And that’s her father.’ A picture came up of a stern, strong, blond man wearing a crown. ‘Henry Plantagenet. King Henry the Second of England.’

‘I don’t understand.’

‘The only Henry and Eleanor de Poitiers in France are them.’ Again Lacoste pointed to the screen, now split and showing both old drawings.

‘But it doesn’t make any sense,’ said Gamache, struggling with the information.

‘You’ve never been a teenage girl.’

‘What do you mean?’

‘This is the sort of thing that appeals to romantic girls. A strong and tragic queen, a noble king. The Crusades. Eleanor de Poitiers actually went on crusade with her first husband. She created an army of three hundred women and rode bare-breasted part of the way. At least, that’s the story. She eventually divorced Louis of France and married Henry.’

‘And lived happily ever after?’

‘Not exactly. He put her in prison, but not before she’d had four sons. Richard the Lionheart was one. She was amazing.’ Lacoste gazed at the woman on horseback and imagined being part of her army. Riding bare-breasted through Palestine in the wake of this remarkable woman. It wasn’t just teenagers who were drawn to Eleanor of Aquitaine.

‘Richard the Lionheart?’ Gamache asked. ‘But no daughter named CC?’

‘Who was a designer living in Three Pines? No. King Henry died in 1189. Eleanor in 1204. So either CC de Poitiers was long overdue for death herself or, just maybe, she was lying. No wonder the entire Sûreté in Paris was laughing at me. Thank God I told them I was Agent Nichol.’

Gamache shook his head. ‘So she made them up. She reached back almost a millennium to create parents. Why? Why would she do it? And why them?’

The two sat in silence for a moment, thinking.

‘So who were her real parents?’ Lacoste finally asked.

‘I think that might be an important question.’

Gamache went to his desk. It was twenty past five. Just time to speak to Lemieux before meeting Dr Harris. He downloaded his messages and dialed the number left by Lemieux.

‘Agent Lemieux,’ came the shouted answer.
