The silence grew upon him, and he stood there uncertainly, listening. Something was wrong. There was no familiar drone of atomic motors, and there should be....

When the shock came, he was hurled completely across the room to the far bulkhead. Yet it wasn't a severe shock. It was as if the ship faltered suddenly and heeled over on her side.

Above him, Standish saw induction and exhaust pipes, coated with sulphur dioxide frost, writhe and twist like so many serpents. The explosion that followed was deafening. The floor buckled upward under the pressure. The door to the cabin was torn from its hinges, and a sheet of flame and a column of smoke gushed inward.

In an instant, Standish understood. The prison ship, well on its voyage from Earth, had entered the danger zone, that part of space swarming with planetoids and miniature planets. A sleepy pilot had failed to make the proper gravitational allowances. They had struck!

The ship was almost over on her beam ends now. It righted slowly, and Standish fought his way into the outer passageway, every muscle tensed for instant action.

The corridor was empty. Gas and smoke searing his nostrils, the Earthman made his way to the companion. Up he climbed. Emerging on the second level, he stood rigid, stark horror gripping him.

The cages were there. Tier after tier of them stretching into the bowels of the space ship as far as the grey light permitted him to see. In those cages, he knew, were men of his own race: Earth soldiers, prisoners of war.

But over each cage the heavy ceiling plates had been ripped free by the force of the explosion, and where the imprisoned men had been, only twisted bars and sheets of arelium steel were visible. The entire level was a tomb of silence.

Standish choked back a sob. His men all dead! Crushed like rats in a trap.

He crossed to the ladder leading to the third and main level, climbing slowly.
