It was clear why Outpost Gog could not report the disaster. The attack had destroyed their one link with the post on this time level; the concealed communicator had gone up with the blast.

"Eleven—" Ashe's finger tapped on the ornate buckle of his wide belt. "We have about ten days to stick it out," he added, "and it seems we may be able to use them to better advantage than just letting you learn how it feels to walk about some four thousand years before you were born. We have to find out—if we can—what happened here and why!"

Ross gazed at the mess. "Dig?" he asked.

"Some digging is indicated."

So they dug. Finally, black with charcoal smudges and sick with the evidences of death they had chanced upon, they collapsed on the cleanest spot they could find.

"They must have hit at night," Ashe said slowly. "Only at that time would they find everyone here. Men don't trust a night filled with ghosts, and our agents conform to local custom as usual. All of the post people could be erased with one bomb at night."

All except two of them had been true Beaker traders, including women and children. No Beaker trading post was large, and this one was unusually small. The attacker had wiped out some twenty people, eighteen of them innocent victims.

"How long ago?" Ross wanted to know.

"Maybe two days. And this attack came without any warning, or Sandy would have sent a message. He had no suspicions at all; his last reports were all routine, which means that if they were on to him—and they must have been, judging by the results—he was not even aware of it."

"What do we do now?"
