Part of him was aware that what he was doing was dangerous, outrageous, ridiculous. The other part told him he was doing something good and brave, and his grandfather would have argued against Dalip’s parents for him to be allowed to do it. That this was his duty, his honour, his right, to risk everything to help his friends.

He was at the same height as the window. He stretched out with his foot, found his next foothold, and slid across the wall, turning his head to the direction of travel. Below him, across the courtyard, the men were still drinking. If they’d looked up and away from the fire, they’d have spotted him, an orange figure spreadeagled against the side of the tower. But they concentrated on the dancing flames and their conversation, and Dalip carried on.

Another move closer. If he reached out now, he could stand on the window ledge. It’d also make him visible to anyone in the room beyond. He listened for voices, and decided that he’d just have to risk it. He eased himself across and got a good handhold on the other side.

There was a curtain over the window, hanging down inside from a rod on the lintel, obscuring him from view – a stroke of luck. He listened again, and when he heard nothing, he quickly slipped through, still behind the curtain, turning sideways and searching for the floor with his foot. He found it. The effort of the last few minutes burned in his muscles, but he’d done it. He made sure he had firm hold of the knife before unclenching his jaw.

He peeked around the side of the heavy curtain. It seemed to be a dimly lit room, and after a moment’s hesitation, he stepped out, knife ready.

There was no one there. He quickly crossed the bare floor to listen at the only door, and only then took notice of what else was there. He was in some sort of store room, with floor-to-ceiling shelves on the walls holding jars and boxes of all sizes and shapes. A table was covered with clutter, things that looked like the results of a primary-school nature ramble: stones rough and smooth, mottled leaves and snapped twigs, the bleached white bones of small animals long-since passed.

He wasn’t there to poke around, though. He lifted the latch on the store-room door and opened it a sliver. The curtain behind him rustled and lifted in the draught, and the wind moaned through, carrying with it the unmistakable tap-tap of someone on the staircase beyond. He eased the door shut and waited for them to pass.

The tapping got louder, and against his expectations he recognised it as the sound of the steward’s silver-topped cane on the stone floor. Dalip held his breath. The tapping stopped with a scratch, and the latch clacked up on its own.
