in
his papers. Just as I reached the door, he looked up and impaled me on
his finger again.

"And don't get any fancy ideas about jumping your contract. We can
attach that bank account of yours on Algol II long before you could draw
the money out."

I smiled, a little weakly, I'm afraid, as if I had never meant to keep
that account a secret. His spies were getting more efficient every day.
Walking down the hall, I tried to figure a way to transfer the money
without his catching on--and knew at the same time he was figuring a way
to outfigure me.

It was all very depressing, so I stopped for a drink, then went on to
the spaceport.

By the time the ship was serviced, I had a course charted. The nearest
beacon to the broken-down Proxima Centauri Beacon was on one of the
planets of Beta Circinus and I headed there first, a short trip of only
about nine days in hyperspace.

To understand the importance of the beacons, you have to understand
hyperspace. Not that many people do, but it is easy enough to understand
that in this _non_-space the regular rules don't apply. Speed and
measurements are a matter of relationship, not constant facts like the
fixed universe.

The first ships to enter hyperspace had no place to go--and no way to
even tell if they had moved. The beacons solved that problem and opened
the entire universe. They are built on planets and generate tremendous
amounts of power. This power is turned into radiation that is punched
through into hyperspace. Every beacon has a code signal as part of its
radiation and represents a measurable point in hyperspace. Triangulation
and quadrature of the beacons works for navigation--only it follows its
own rules. The rules are complex and variable, but they are still rules
that a navigator can follow.

For a hyperspace jump, you need at least four beacons for an accurate
fix. For long jumps, navigators use as many as seven or eight. So every
beacon is important and every one has to keep operating. That is where I
and the other trouble-shooters came in.

We travel in well-stocked ships that carry a little bit of everything;
only one man to a ship because that is all it takes to operate the
overly efficient repair machinery. Due to the very nature of our job, we
spend most of our time just rocketing through normal space. After all,
when a beacon breaks down, how do you find it?

Not through hyperspace. All you can do is
