His boots scuffled at the rough stone, the hemp bit at his hands, his arms burned at the work, and all the while he did his best to keep his rasping breath quiet. The battlements edged closer, then closer, then he was there. He hooked his fingers onto the stone and peered over. The walkway was empty, both ways. He slipped over the parapet, sliding a knife out, just in case. You can never have too many knives, and all that. He checked the grapple was caught firm, then he leaned over, saw Dow at the bottom looking up, Grim with the rope in his hands, one foot on the wall, ready to climb. Dogman beckoned to him to say come, watched him start up, hand over hand, Dow holding to the bottom of the rope to stop it flapping. Soon enough he was halfway—

'What the fuck—'

Dogman jerked his head left. There were a pair of Thralls not far off, just stepped out from a door to the nearest tower and onto the wall. They stared at him, and he stared back, seemed like the longest time.

'There's a rope here!' he shouted, brandishing his knife around and making like he was trying to cut it away from the grapple. 'Some bastard's trying to climb in!'

'By the dead!' One came running, gawped down at Grim swinging around. 'He's coming up now!'

The other one pulled his sword out. 'Don't worry 'bout that.' He lifted it, grinning, ready to chop through the rope. Then he stopped. 'Here—why you all muddy?'

Dogman stabbed him in the chest, hard as he could, and again. 'Eeeeee!' wailed the Thrall, face screwed up, lurching back against the battlements and dropping his sword over the side. His mate came charging up, swinging a big mace. Dogman ducked under it, but the Thrall barrelled into him and brought him down on his back, head cracking on stone.

The mace clattered away and they wrestled around, the Thrall kicking and punching while Dogman tried to get his hands round his throat, stop him from calling out. They rolled over one way, then back the other, struggled up to standing and tottered about down the walkway. The Thrall got his shoulder in Dogman's armpit and shoved him back up against the battlements, trying to bundle him over.

'Shit,' gasped the Dogman as his feet left the ground. He could feel his arse scraping the stone, but still he clung on, hands tight round the Thrall's neck, stopping him getting a good breath. He went up another inch, felt his head forced back, almost more weight on the wrong side of the parapet than the right.
