2.20am. I’m riding home on the 2.08 from London Victoria. I didn’t even know trains still ran at that ungodly hour of the morning. Apparently they do: one every hour at eight minutes past the hour. They lock the station until ten minutes or so before the train leaves, and there’s quite a crowd loitering outside the gates just before they open them. Three Bridges is clearly the place to be at two in the morning. Who’d have thought it?

I did some much needed “getting out” today. With a couple of exceptions I’ve more or less turtled for four years or more. I guess that’s the nature of life in a boarding school: whereas most other folks can play their weekends and snatch evenings here and there, in teaching you block out your free time by your holidays…

The chap two seats ahead is fast asleep in his seat. His phone alarm is going off for the third time. The lads on the row of seats opposite looked annoyed at first, but one of them has struck up a conversation with the sleeper and asked if he’s going to get home OK.

I killed some time with my sketchbook on the Underground this afternoon, and again waiting in the street in Holborn before the party. A homeless man wandered over, cap in hand, to ask for help. Normally I have to admit I’d probably turn a callous blind eye, but something about London draws me in, makes me think differently. I asked for his name and we got talking. He said his name was James, and that he was trying to find a place that would take both him and his dog for the night. I gave him something to start his hunt – for once I happened to have a loose note on me. We shook hands and he set off at a run.

I didn’t have to make the trek home quite so soon. A friend offered me the key to his place for the night, if I could find my way there. I turned it down, partly out of habit, partly out of pride, and partly because of James. Having such an easy solution in London when so many are out on the streets… for some reason it didn’t sit right. You think in a different key in the small hours.

I remember sleeping rough in the wastelands beyond Almeria years ago. Gaunt from a month of under budgeting and undereating and feeling hollow. I remember the fear of that first night, the isolation. It could never compare to the real thing, of course, but I was young, foolhardy, and I wanted to have an idea of how it felt. One night I was curled up in the dunes when a couple of cars rolled up onto the beach around two in the morning. Men with flashlights climbed out and scanned the beach. I got the jitters and decided to move – they were probably night-fishing, but your brain plays all kinds of tricks at night. I don’t think I’ll ever forget the genuine pit-of-my-stomach terror when, barely a few yards down the beach, I saw two of the torch beams slowly sweep the beach and lock onto me. I ran. My God, did I run. I don’t think I’ve ever run so fast in my life. I must have gone at least a kilometre or more before I collapsed in the dunes.

Almeria seems a long way away. London is surprisingly busy in the small hours. Not the city that never sleeps, per se, but one that keeps at least one eye open all night. Offices lit up, calendars and Macs on desks. Lads coming home from the lash. A girl tottering home on heels, makeup streaming, eyes weeping. And many, many sleeping bags in doorways.

It felt good to go out again. I haven’t danced in years – not since university, I shouldn’t wonder. And as it’s London, the music was both a) quality and b) perfect for dancing shoes. I should do this again sometime. Not that I’d make a habit out of catching the 2.08, though.

Gatwick Airport ahead. Only another five minutes or so to go, and then it’s the long walk back through the forest. I’ll probably be in bed by 4, with or without the moonlight to guide me – I’ve made that journey so often I could probably do it blind.

I’ll sign off now so my phone has enough juice for another chapter or so of Michelle Paver’s Ghost Hunter on Audible. That will take me at least as far as the forest – there, at least, I will feel safe again. BB x
