All my being was in my ears. I just stood there and listened. I could hear die slap of waves against the hull, the occasional low metallic rumble as the Nantesville worked against wind and tide on its moorings, the low moan of the strengthening night wind in the rigging and, once, the far-off lonely call of a curlew. Lonesome sounds, safe sounds, sounds of the night and nature. Not the sounds I was listening for. Gradually, these sounds too became part of the silence. Foreign sounds, sounds of stealth and menace and danger, there were none. No sound of breathing, no slightest scrape of feet on steel decks, no rustle of clothing, nothing. If there was anyone waiting out there he was possessed of a patience and immobility that was superhuman and I wasn't worried about superhumans that night, just about humans, humans with knives and guns and chisels in their hands. Silently I stepped out over the storm sill.

I've never paddled along the night-time Orinoco in a dug-out canoe and had a thirty-foot anaconda drop from a tree, wrap a coil around my neck and start constricting me to death and what's more I don't have to go there now to describe the experience for I know exactly what it feels like. The sheer animal power, the feral ferocity of the pair of huge hands that closed round my neck from behind was terrifying, something I'd never known of, never dreamed of. After the first moment of blind panic and shocked paralysis, there was only one thought in my mind: it comes to us all and now it has come to me, someone who is cleverer and stronger and more ruthless than I am.

I lashed back with all the power of my right foot but the man behind me knew every rule in the book. His own right foot, travelling with even more speed and power than mine, smashed into the back of my swinging leg. It wasn't a man behind me, it was a centaur and he was shod with the biggest set of horseshoes I'd ever come across.
