He glared at me, and then slammed home all the long steel levers, one after the other. Ivor shook and shuddered. Tony started shovelling his crystallised tachyons into the fuel chamber again. Giles considered this thoughtfully.

“I hadn’t realised you came from so far back in the past . . .”

“One more word out of you, and you can get out and push,” said Tony, shovelling for all he was worth.

“Don’t bother the engineer while he’s working,” I said to Giles. “He’ll just get tetchy.”

A whole bunch of energy beams hit the protective screen all at once, and Molly cried out in pain, her eyes squeezed shut with the strain of maintaining the field. A trickle of blood burst out from under her left eyelid. Tony slammed the fuel chamber door shut, and then threw the throttle all the way open, muttering a mixture of prayers, obscenities, and encouragements to Ivor under his breath. Ivor lurched forward, sending us all staggering, and then headed for the Merlin Glass, which was once again hovering in the air before us. One of the airships shot at it, and the energy beam rebounded straight back to blow the airship out of the sky. It figured that anything built by Merlin Satanspawn would be able to defend itself.

The other airships increased their fire on Ivor as he began to move, chugging unevenly through the thick snow, but none of the attacks got through, even as Molly’s face ran with sweat, and more blood ran from her clenched shut eyes. Ivor slowly built up speed, the snowy waste slipping away behind us, until the Merlin Glass seemed to sweep forward and swallow us up; and just like that we left the alien world behind us, plunging back through the other side of space and time, heading for home.

Molly relaxed with a great shuddering sigh and leaned exhausted against the inner cab wall. Her eyes were still closed, but the bleeding seemed to have stopped. I sat down beside her, and gently cleaned the sweat and blood from her face with my handkerchief. She smiled slightly, just to let me know she was glad I was there.
