Of the world on the far side of the partition he knew nothing, but he realized that there was a world. Should he make a rush for it before the enemy had regained courage? Even so, where should he rush to? Was he likely to find an exit amid altogether strange surroundings? Could he block the hole? Rats had done such things before now, but it was only deferring the evil hour, and what time would he have to do it in? The question was answered for him. The echo of the watchman’s step had barely ceased, before the hole at the base of the door was, for a moment, obscured.

They came in jerky disorder. First a young, loose-limbed stripling. He was barely out before he was back again, throwing up the pink soles of his hind feet, and flicking the woodwork with his belated tail. Then a kaleidoscopic succession of suspicious faces. The light danced on the floor as each thrust his neighbour aside, thrust his head like lightning through the opening, and as quickly withdrew it. They were masters of scouting, these brown barbarians. Sometimes one, bolder or younger than the rest, would steal a foot within the cellar. Sometimes, for minutes together, all would be quiet, the light patch on the floor the only thing amiss. The black rat never moved his eyes from that light.

It was an hour before the chieftain himself appeared. He squeezed through the opening, but, for all his bulk, came quickly. Once clear, he dropped upon his haunches, and knit his fists before him. The position showed him at his best. Crouched or in motion, the clumsy angles of his body were forced into relief. As he sat back, the curves softened, and, as far as brown rat could be, he was imposing. For some moments he sat immovable, facing the darkness, then he turned, and, with one eye always fixed behind him, passed slowly out of sight.

There was a long silence after this. The light patch on the floor seemed to grow in intensity. By its dull reflection, the black rat could just distinguish his own whiskers. It fascinated him. He stole halfway across the floor towards it, and paused. As he paused, it was blotted out once more.

the position showed him at his best.

He was being watched. Before he was back in his corner, three of the enemy were through the breach. Five more followed. Then in quick confusion a dozen. Then a dozen more. The Hanoverian army was spreading its wings.

Their actual number he never knew. Perhaps, for the credit of his family, it was as well. Reflection would assuredly have put resistance, and even hope, out of the question. As it was, he came forward with absolute indifference. His breeding again stood him in good stead. Of all the host he was the least uneasy. In the middle of the floor he stopped abruptly, confronting the situation. Fifty rats were in the cellar now, and there was not a rustle among them.

He had calculated exactly where to stop. It was a foot beyond the normal take-off of the grown rat. He flung his head round, put all the force he possessed into his hind legs, and leapt, upwards and backwards, towards the shelf. He caught it with his fore-paws, scrambled on to it, and, for the moment, was safe. He was only just quick enough. As his eyes turned, the brown rats had rushed forward, and, even as he clutched the ledge, he heard them pattering against the wall.

The floor below was a raging sea of rats; rats leaping over one another, jostling, biting, tearing. To the silence of a moment before had succeeded a babel of shrieks and hisses. But there were no jumpers among them like himself. He passed quietly along the ledge above them, through the entrance of the run, and up to its blocked extremity. There he braced his back against the concrete and waited.
