A shot rang out above the yells.  Gale heard the jingle of breaking glass.  The room darkened perceptibly.  He flashed a glance backward.  The two cowboys were between him and the crowd of frantic rebels.  One cowboy held two guns low down, level in front of him.  The other had his gun raised and aimed.  On the instant it spouted red and white.  With the crack came the crashing of glass, another darkening shade over the room.  With a cry Gale slung the bleeding Rojas from him.  The bandit struck a table, toppled over it, fell, and lay prone.

Another shot made the room full of moving shadows, with light only back of the bar.  A white-clad figure rushed at Gale.  He tripped the man, but had to kick hard to disengage himself from grasping hands.  Another figure closed in on Gale.  This one was dark, swift.  A blade glinted—­described a circle aloft.  Simultaneously with a close, red flash the knife wavered; the man wielding it stumbled backward.  In the din Gale did not hear a report, but the Mexican’s fall was significant.  Then pandemonium broke loose.  The din became a roar.  Gale heard shots that sounded like dull spats in the distance.  The big lamp behind the bar seemingly split, then sputtered and went out, leaving the room in darkness.

Gale leaped toward the restaurant door, which was outlined faintly by the yellow light within.  Right and left he pushed the groping men who jostled with him.  He vaulted a pool table, sent tables and chairs flying, and gained the door, to be the first of a wedging mob to squeeze through.  One sweep of his arm knocked the restaurant lamp from its stand; and he ran out, leaving darkness behind him.  A few bounds took him into the parlor.  It was deserted.  Thorne had gotten away with Mercedes.

It was then Gale slowed up.  For the space of perhaps sixty seconds he had been moving with startling velocity.  He peered cautiously out into the plaza.  The paths, the benches, the shady places under the trees contained no skulking men.  He ran out, keeping to the shade, and did not go into the path till he was halfway through the plaza.  Under a street lamp at the far end of the path he thought he saw two dark figures.  He ran faster, and soon reached the street.  The uproar back in the hotel began to diminish, or else he was getting out of hearing.  The few people he saw close at hand were all coming his way, and only the foremost showed any excitement.  Gale walked swiftly, peering ahead for two figures.  Presently he saw them—­one tall, wearing a cape; the other slight, mantled.  Gale drew a sharp breath of relief.  Throne and Mercedes were not far ahead.

From time to time Thorne looked back.  He strode swiftly, almost carrying Mercedes, who clung closely to him.  She, too, looked back.  Once Gale saw her white face flash in the light of a street lamp.  He began to overhaul them; and soon, when the last lamp had been passed and the street was dark, he ventured a whistle.  Thorne heard it, for he turned, whistled a low reply, and went on.  Not for some distance beyond, where the street ended in open country, did they halt to wait.  The desert began here.  Gale felt the soft sand under his feet and saw the grotesque forms of cactus.  Then he came up with the fugitives.
