The shack was dark.

Instead of knocking, Muldoon walked around to the back and peered
through the single window at the rear. He could see nothing. Now isn't
this just dandy, he thought. Drive all the way out here, and nobody's at
home. Damn! He went around to the front and started back to the car. His
attention was caught by a greenish glow of light from the far end of the
dump heap.

His curiosity aroused, Muldoon warily made his way through the metal
litter until he was close enough to make out the source of the light. It
came from the center of a shallow area that had been cleared of rubble.
A rusted misshapen mass of metal lay in the center of the cleared space.
The greenish glow was coming from an opening in the mass.

Muldoon crept closer until he was able to make out details. Not too many
but enough to give him an idea of the size and general shape of the
thing. But what really held him were the figures of Robert and Evin
Reeger.

He saw them quite distinctly.

One of the twins was bent over a machine of some sort. There were
levers, gears, and rollers mounted on a webbed platform no larger than a
rather oversized typewriter. Muldoon's eyes went wide at the sight of
the greenbacks coming in a steady stream from the interior of the
machine and falling into a box at the side. He could see very little
else that was in the room, other than the brother of the twin at the
machine. He was on the far side of it, fiddling with something hidden.

Muldoon stared in fascination for another minute, then carefully made
his way back to the car. He had parked it within the growth of scrub
trees and bushes. He started it, turned the headlights on, and drove
slowly out into the open and up to the shack. He honked his horn loudly
a couple of times and got out of the car and walked up to the shack and
tried the door. It was closed.

Presently the figures of Evin and Robert Reeger came into view from the
direction of the dump heap. Muldoon's figure was outlined in the glow of
the headlights. Muldoon noticed the brief case one of them was carrying.

"Ah, there, Muldoon," Muldoon had recognized Robert's voice.

"Hello, Mr. Reeger. Thought I'd come by and let you know how I've been
doing."

Evin, who was carrying the brief case, unlocked the door and switched on
the light. The other two followed him into the room. Robert Reeger
motioned for Muldoon to take the sofa. Evin went into the other room.

"Well, my boy," Robert sa
