No-one knew how or why Timeslips operated, though down the years people had come up with some really disturbing theories. All the Authorities ever did was set up barriers and warning signs around the affected areas and wait for the Timeslips to disappear again. There was a Really Dangerous Sports Club, whose members would come running from all directions to dive into a Timeslip, just for the thrill of it. Danger junkies, for whom the thrill of setting themselves on fire and jumping off high buildings just didn't do it for them any more. They must like what they find at the other end of their rainbow, because none of them ever come back to complain.

There was only one person in the Nightside powerful enough to send someone through Time with any degree of accuracy, and that was Old Father Time. A Power and a Domination so mighty, his services could not be bought or commanded by anyone, very definitely including the Authorities. You had to approach him in person, in the Time Tower, and convince him that your trip was ... worthwhile. And given my chequered reputation, I was going to have to be very persuasive. I was relying on Cathy and her computers to come up with the necessary ammunition.

(The Authorities did operate their own Time Tunnel for a while, back in the 1960s, but apparently it was never very accurate, and was shut down under something of a cloud.)

I finally tracked down the address Cathy had given me, and was surprised to find my office was located in a

reasonably up-market area. There were more business offices than establishments, and the streets boasted a much better class of sinner. Rent-a-cops lounged around in gaudy private uniforms, but somehow always found something else to be interested in whenever I looked in their direction. My office was in a tall high-tech building, all gleaming steel and one-way windows. I gave my name to the snotty simulacrum face embedded in the front door, and Cathy buzzed me in. I sneered at the face and swaggered into the oversized lobby like I owned it.
