Odile, as he’d stepped into the fresh air from the cloying aromas of the organic store, had shouted a phrase that still resonated in his ears.

‘Watch out for bears,’ she’d sung cheerily after him.

He’d picked up a stick when he’d entered the woods. To knock the bear on the nose. Or was that sharks? Well, he was ready either way. The bear could always use the stick as a toothpick after eating him.

He had a gun but he’d been so thoroughly trained by Gamache not to ever take it out unless he was certain to use it, it remained holstered.

Beauvoir had watched enough news reports about bear attacks to know that black bears weren’t generally dangerous, unless you got between mother and child. He also knew they were dangerous if startled. So screaming ‘Monsieur Sandon’ had taken on a dual purpose.

‘Monsieur Saaaandonnnn.’

‘I’m here,’ came the sudden response. Beauvoir stopped and looked around.

‘Where?’ he yelled.

‘Over here. I’ll find you.’

Now Beauvoir heard footsteps through the autumn leaves, and the cracking of twigs. But he saw no man. The sound grew louder and still no man. It was like the approach of a ghost.

Damn, shouldn’t have thought that, thought Beauvoir, feeling his anxiety rise. I don’t believe in ghosts. I don’t believe in ghosts.

‘Who are you?’

Beauvoir turned round and on the top of a slight rise stood a massive man. Broad-chested, powerful and tall. He wore a shaggy knitted hat and his red beard stuck out in all directions. He was covered in mud and bark.

Yeti. Big Foot. There was some old creature his grandmother had told him about. The Green Man. Half man, half tree. This was him.

Beauvoir gripped his stick.

‘Inspector Beauvoir, Sûreté du Québec.’

It had never sounded more feeble. Then the Green Man laughed. Not a malicious, ‘I’m going to tear you limb from limb’ laugh. But a laugh of genuine amusement. He came down the small hill, winding gracefully between old growth trees and saplings.

‘Thought you were a tree talking to me just now.’ He put out his massive, filthy hand and Beauvoir took it. He too laughed. It was hard not to feel cheerful in this man’s company. ‘Though they’re generally a little less obvious when they speak.’

‘The trees?’

‘Oh, yes. But you’re probably not here to talk about them. Or to them.’ Sandon reached out and put his hand squarely on a massive trunk beside him. Not leaning against it, but as a sort of touch-stone. Even without Odile’s obscure comments Beauvoir could tell this man had a singular relationship with the woods. If Darwin had concluded man evolved from trees, Gilles Sandon would be the missing link.

‘That’s true. I’m investigating the murder of Madeleine Favreau. I believe—’ Beauvoir stopped. The large man in front of him had taken a step back as though Beauvoir had physically pushed him.

‘Her murder? What are you saying?’

‘I’m sorry, I assumed you knew. You do know she’s dead.’

‘I was there. I took her to the hospital.’

‘I’m afraid the coroner’s report says her death wasn’t natural.’

‘Well of course it wasn’t natural. There was nothing natural about that night. Should never have invited those spirits into the room. It was that psychic.’

‘She’s a witch,’ said Beauvoir and couldn’t believe he’d let that out. Still, it was the truth. He thought.

‘Not surprised,’ said Sandon, recovering himself a little. ‘Should have known better. All of us, but especially her. There are strange things done in this world, son. And strange things done in the next. But I’ll tell you something.’ He stepped closer to Beauvoir and leaned down. Beauvoir braced himself for the stench of hard work and little soap. Instead this man smelled of fresh air and pine. ‘The strangest is what happens between the worlds. That’s where those spirits live, trapped. Not natural.’

‘And listening to trees is?’

Sandon’s face, so stern and troubled for a moment, smiled once again. ‘One day you’ll hear them. In the quiet, some whisper you’d mistaken for the wind all your life. But it’ll be the trees. Nature is talking to us all the time, it’s just hearing that’s the problem. Now I can’t hear water or flowers or rocks. Well, actually, I can but just a little. But trees? Their voices are clear to me.’

‘And what do they say?’ Beauvoir couldn’t quite believe he’d asked the question and certainly couldn’t believe he actually wanted to know the answer.
