Snap, who was in the group near Grantline at the windows, gasped.

"God! Was that Gregg Haljan who fell?"

No one could say. No one answered. Outside, on the camp-ledge, another helmeted figure now became visible. It was not far from the main building when Grantline first noticed it. It was running fast, bounding toward the spider-staircase. It began mounting.

And now still another figure became visible—the giant Martian again. He appeared from around the corner of the main Grantline building. He evidently saw the winner of the combat on the cliff, who now was standing in the Earthlight, gazing down. And he saw, too, no doubt, the second figure mounting the stairs. He stood quite near the window through which Grantline and his men were gazing, with his back to the building, looking up to the summit. Then he ran with tremendous leaps toward the ascending staircase.

Was it Haljan standing up there on the summit? Who was it climbing the staircase? And was the third figure Miko?

Grantline's mind framed the questions. But his attention was torn from them, and torn even from the swift silent drama outside. The corridor was ringing with shouts.

"We're imprisoned! Can't get out! Was Haljan killed? The brigands are outside!"

And then an interior audiphone blared a call for Grantline. Someone in the instrument room of the adjoining building was talking:

"Commander, I tried the telescope to see who got killed—"

But he did not say who got killed, for he had greater news.
