I woke early and spent a few minutes listening to the sparrows, then made a cup of tea and settled down to work. With a first draft complete, The Hollows is off to one side, ready for a redraft when it has finished steeping. At something of a loss for what to do, I worked on an older piece, making some overdue tweaks. It was slow, frustrating progress and I was relieved, an hour or so later, when Dora thundered on the ceiling overhead. She clattered down the stairs and burst into the room, as she does every morning, and threw herself at me.

‘Morning sweetheart. It’s good to see you. Did you have any dreams?’

‘Yes.’

‘Good dreams or bad dreams?’

‘It was a bad dream.’

‘Oh no. What happened?’

Her face fuzzled as she remembered it.

‘There was a big swamp. And a little girl went into the swamp, and she stole a ribbon.’

I frowned. This reminded me of something. Dora continued:

‘And the little girl was chased in the swamp by a very bad man.’

I realised what she was saying. I knew what she would say next. My skin began to tingle, crawling upwards from my ankles.

‘And the bad man took the ribbon, and he took the little girl as well, and then there was nothing but the swamp.’

My four-year-old daughter had just relayed to me the plot of the first chapter of The Hollows. Which would be fine, except for the fact that no one else knows it but me. I haven’t shared it with anyone. No one has read it, and I’m the only person in the entire world who knows what happens.

I’ve been ransacking my brain to work out what happened. I’ve never told Dora any part of the story, and she can’t read for herself. Mon hasn’t seen it yet, so she couldn’t have told Dora either, and no one else has access to my computer. I have no idea how she knew this part of the plot. There must be a rational explanation, but I can’t work it out.

There’s just no way. There is simply no way it could have happened.

And yet it did.

A woman always, always tripped on the bottom tread of the stairs in her new house, her muscle memory convinced and compelled to make an extra step for a stair that wasn’t there. This happened for years. When the house was renovated, and the floor was lifted, the builders discovered an extra step at the bottom of the flight. People wake from comas speaking Latin, or dream across a continent of their brother drowning at sea, and wake to bad news on the phone.

I don’t believe in ghosts as sentient beings. I don’t believe in the supernatural as an anthropology. But human imagination is an engine of staggering power, and we are utterly corruptible. The weight of human history drops away below our feet, and we walk in the shadows and the hollows of what has gone before. Like crossing a clay field after the rain, it sticks to our feet in clumps.

Holloways are ancient droving roads. The weight of carts and cattle through the roads caused the ground below to erode and sink, even as the verges to the side of the road stayed the same. Protected from the passing herds, trees grew on the verges and knotted overhead, while below, the path continued to erode, ground away by centuries of cattle, and so, over time, the roads became tunnels: hollow ways.

That’s where we are, all of us. The trees have been cut and the verges levelled and all of it coated with tarmac, but we still walk along the holloways. A sideways glimpse is all it takes to see the fleeting, teeming strata of the lives we’ve lived before.
