The last sight he saw, as he chanced a look over his shoulder, was the sight of all intelligence draining out of Bowdler's face. The charge had hit him.

Slamming the door on the scene, Comstock ran, and as he ran he screamed to Grundy, "The R.A. killed him! He killed Bowdler."

Ten feet away the news made Grundy pause and almost stumble, but Comstock saw him recover and then run on. He yelled back to Comstock. "Tough. He was a good guy. But we gotta keep goin' or we'll be killed too."

The endless corridor through which they were running was dank and it was dark. There was no curve, no up or down. It was simply a black hole through which they ran and ran, and kept on running. When Comstock thought that he would never be able to breathe again, that his muscles could no longer bear his weight, that he must slump in a helpless heap and wait for death, he heard Grundy snap, "Ten feet more."

The words shot a new charge of adrenalin into Comstock. With a last surge of strength he darted after his friend's back. As a matter of fact he lunged full tilt into it because the darkness was so complete he could not see his hand before his face.

Grundy grunted, "Hold everything. I have to find the latch."

Another moment that seemed to stretch out far beyond the end of eternity and then, just as Comstock's strained ears heard footsteps running behind him in the dark. Grundy said, "There it is." And a door opened. Beyond was further darkness, but it was not as complete as the stygian blackness they were leaving. Falling through the doorway, Comstock fell to his face as Grundy slammed the door behind them.

"That'll hold the R.A. for a minute and that's all we need."

Lifting his head, forcing his trunk upwards from the ground, Comstock saw that they had come out on a street ... he looked at it while his breath raced in and out of his tortured lungs ... the street was familiar. It was the one that housed the b.....l to which he repaired once a month.

At the curb waiting, was an R.A.'s carriage. The team of astrobats waited patiently in harness, their too-pointed faces and four ears heavy with menace towards anyone who dared to approach them.
