The buildings were mostly stone and timber, a mere two or three storeys high; basic blocky structures with a few lingering traces of Roman architecture. What style there was, was mostly Celtic with some Saxon, plus a whole bunch of stuff I didn't recognize. There were no pavements, only two thick streams of human traffic on either side of a deeply churned dirt road. The traffic in the middle wasn't moving much faster, being mostly horse-drawn

wagons, and rough carts pulled by equally rough people. Hulking covered wagons groaned along, their heavy wooden wheels sinking deeply into the muddy road. There was mud and shit and filth everywhere, and flies hung in thick clouds on the smoky air. Now and again a better-dressed person would come riding through on a caparisoned horse, driving everyone else out of the way. And finally, a hunchbacked drover came along, riding a mule and driving a herd of miniature mammoths. They were about a foot or so high, cheeping cheerfully as they ploughed through the mud.

"Aw, cute," said Suzie, unexpectedly. Tommy and I both looked at her, and she stared us down with great dignity.

We looked out into the street again. "Judging by the architecture, I'd say we've ended up somewhen in the sixth century," said Tommy. "The Roman Empire has declined and fallen, and the dominant Celts are fighting a war against invading Saxons." Suzie and I looked at him, and he bristled. "I've read a lot about this period. It's really very interesting."

"I don't care if it's downright fascinating, we shouldn't be here," said Suzie. "We're at least five hundred years short of when we were supposed to arrive. Somebody screwed up."

"It can't be a mistake," said Tommy. "Old Father Time doesn't make mistakes. In fact, he is famous for not making mistakes."

"He didn't," I said. "Somebody else interfered."

Rage blinded me for a moment, and I hit out at the wall beside me, hurting my hand on the solid brick and not caring, almost relishing the pain. I tried to say something, but the anger flooding through me clenched my teeth, and it came out as a growl. Tommy started to back away. The rage pulsed in my gut like a red-hot coal, bending me over till I was glaring at the filthy ground. Hot, helpless tears burned in my eyes, and I hit out at the wall again.

Suzie moved in close beside me, murmuring quiet words, bringing me back with her calm, steady presence. I was breathing hard and rough, as though I'd just been hit; but Suzie's reassuring presence slowly got through to me, and I straightened up again. I pushed the anger into the back of my head, to be released later, when I had someone to take it out on. I took a deep breath and nodded my thanks to Suzie. She nodded back. She understood.

I looked down the alley at Tommy, who stared back uncertainly. "It's all right," I said, in my best reasonable voice. "I got a little upset there, for a moment, but I'm all right now."
