He took a step toward the side entrance.

"Hands up, there!" shouted the plain-clothes man. "And when I say hands up I mean it! Which one of you's Chestnut?"

"You're mad!" cried Este. "We're British subjects. We're not involved in this affair in any way!"

A woman screamed somewhere, and there was a general movement toward the elevator, a movement which stopped short before the muzzles of two automatic pistols. A girl next to Rags collapsed in a dead faint to the floor, and at the same moment the music on the other roof began to play.

"Stop that music!" bellowed the plain-clothes man. "And get some earrings on that whole bunch—quick!"

Two policemen advanced toward the party, and simultaneously Este and the other aides drew their revolvers, and, shielding the prince as they best could, began to edge toward the side. A shot rang out and then another, followed by a crash of silver and china as half a dozen diners overturned their tables and dropped quickly behind.

The panic became general. There were three shots in quick succession, and then a fusillade. Rags saw Este firing coolly at the eight amber lights above, and a thick fume of gray smoke began to fill the air. As a strange undertone to the shouting and screaming came the incessant clamor of the distant jazz band.

Then in a moment it was all over. A shrill whistle rang out over the roof, and through the smoke Rags saw John Chestnut advancing toward the plain-clothes man, his hands held out in a gesture of surrender. There was a last nervous cry, a chill clatter as some one inadvertently stepped into a pile of dishes, and then a heavy silence fell on the roof—even the band seemed to have died away.

"It's all over!" John Chestnut's voice rang out wildly on the night air. "The party's over. Everybody who wants to can go home!"

Still there was silence—Rags knew it was the silence of awe—the strain of guilt had driven John Chestnut insane.
