Back in Jason's office, the desk sergeant reported as Jason came in. "Funny thing. That there tracer started to hum again soon after you was out for a while. Quit again 'bout five minutes ago, though."

Jason gritted his teeth, banished the sergeant, and spent five minutes alone gripping the edge of his desk. Then he yanked Lab Nine's silent genius down to his office. That didn't help for the tracer stayed asleep. Not even a hiccup rewarded Moglaut's most active efforts on Lonnie's wave length. On others, fine. Through the night and on into the next day, Jason kept Moglaut at work.

Late in the morning, Authority at Peiping televised publicly that the Mace of Alexander was gone from its satin pillow in the proof-glass case in the alarm-wired room off the machine-weapon-guarded main corridor of the security-policed Temple of Mankind.

The Mace, symbol of Alexander's power, was a pretty little baton barely two feet long. Its staff was mastodon ivory, the paleontologists had determined. One end sported a solid ball of gold hardly as big as a fist; studded with rubies, but none set quite so close as to actually touch.

The other end, balancing the ball of gold, mounted the largest single polished emerald crystal in the discovered universe. Neither the Moon or Mars had produced anything in the emerald line equivalent to what had come out of the mists of Earthly history.


Disregarding the bulletin, Jason kept Moglaut at the servo-tracer. In the night's smallest hours it began placidly to hum on Lonnie's aura again.

"What happened?" Jason said. "What did you do?"

Moglaut shrugged.

"You must have done something. What was it?"
