After a time they came to an open park, beyond which, on a prominence, with the lake behind, stood a large building that the Chemist had already pointed out to them as the king's palace.

Oteo led them swiftly into a side street to avoid the dense crowd around the park. Making a slight detour they came back to it again—much nearer the palace now—and approached from behind a house that fronted the open space near the palace.

"Friend of the Master—his house!" Oteo explained as he knocked peremptorily at a side door.

They waited a moment, but no one came. Oteo pushed the door and led them within. The house was deserted, and following Oteo, they went to the roof. Here they could see perfectly what was going on around the palace, and in the park below them.

This park was nearly triangular in shape—a thousand feet possibly on each side. At the base of the triangle, on a bluff with the lake behind it, stood the palace. Its main entrance, two huge golden doors, stood at the top of a broad flight of stone steps. On these steps a fight was in progress. A mob surged up them, repulsed at the top by a score or more of men armed with swords, who were defending the doorway.

The square was thronged with people watching the palace steps and shouting almost continuously. The fight before the palace evidently had been in progress for some time. Many dead were lying in the doorway and on the steps below it. The few defenders had so far resisted successfully against tremendous odds, for the invaders, pressed upward by those behind, could not retreat, and were being killed at the top from lack of space in which to fight.

"Look there," cried the Big Business Man suddenly. Coming down a cross street, marching in orderly array with its commander in front, was a company of soldier police. It came to a halt almost directly beneath the watchers on the roof-tops, and its leader brandishing his sword after a moment of hesitation, ordered his men to charge the crowd. They did not move at the order, but stood sullenly in their places. Again he ordered them forward, and, as they refused to obey, made a threatening move towards them.

In sudden frenzy, those nearest leaped upon him, and in an instant he lay dead upon the ground, with half a dozen swords run through his body. Then the men stood, in formation still, apathetically watching the events that were going on around them.

Meanwhile the fight on the palace steps raged more furiously than ever. The defenders were reduced now to a mere handful.

"A moment more—they'll be in," said the Doctor breathlessly. Hardly had he spoken when, with a sudden, irresistible rush, the last of the guards were swept away, and the invaders surged through the doorway into the palace.
