‘We are, I suppose,’ said Mika, standing back again to view her work. ‘But Hubris is going to be here some time. It needs parts brought from Minostra, and they’ll have to come through the runcible. Not until then will it be able to leave orbit.’ She placed the head of the welder back in its sterilizing holder and pushed the wheeled unit a little way back from the table. ‘Cellweld Inc.’ was the wording of the logo on this device, which was a silvered box on top of a wheeled trolley. A touch-console was mounted in the top of the box, and from the side of it issued a skein of pipes and cables. These terminated in a head that could take any of the racked adaptors stored underneath the box. Mika selected something that looked like a small glass spade. ‘I’ve clamped the breaks just to give some support to the welds. I don’t suppose you’ll be resting for a while yet. The clamps will take a year to dissolve; plenty of time for your ribs to completely heal. I’ve dealt with most of the internal tissue damage. I’ll seal you up now.’

Why was it, Cormac wondered, that doctors so relished telling you exactly what they were doing?

The welder droned and there were horrible sucking sounds in his chest. The tugging felt like what an errant child feels when its mother pulls on its coat.

‘There, all done,’ said Mika after what seemed an age. ‘I’ve put a couple of analgesic tabs in, and they’ll dissolve over the next few days. There might be the odd twinge, but you’ll be all right now.’ Behind her he saw the tubes of the remote lung clear of blood and felt the small tugs as she detached each of them. He did not get time to feel any lack of oxygen, for she reached immediately for the back of his neck. Feeling returned suddenly. There was no fading in, no pins and needles; his body just turned back on. He took a gasping breath and the sound of his heart was a sudden thunder.

‘You are all right,’ she said, even in this circumstance not prepared to ask a question. Cormac sat upright and looked down at his chest. It was flawless. Cell-welding left no scars, at least not on the body. He nodded to her. She smiled briefly at him, then turned to Carn.

‘It’s not pain and it’s not physical function,’ she said, resuming a conversation they had been having as Cormac had come in.

Carn opened and closed his silvered hand. ‘I’ve lost PU contact. All I get is normal sensation.’
