The spy's heart was suddenly drained, and the wisp of paper in his hand trembled so that it scattered the quinine about in a thin cloud. Once more he read the note, then held a match to it and scuffed its feathery ash with his feet into the rug beneath his stool. The fortitude which had held Joseph Almer to the Rock in the never-failing hope that some day would bring him the opportunity to do a great service for the fatherland came near crumbling that minute. He groaned.

"Our friends," he whispered, "Woodhouse and Louisa—trapped!"

The warning in the note left nothing open to ambiguity for Almer; there were but four of them—"friends" under the Wilhelmstrasse fellowship of danger—there in Gibraltar: Louisa, the man who passed as Woodhouse, and whose hand was to execute the great coup when the right moment came, himself, and that other one whose place was in Government House itself. From this latter the note of warning had come. How desperate the necessity for it Almer could guess when he took into reckoning the dangers that beset any attempt at communication on the writer's part. So narrow the margin of safety for this "friend" that he must look at each setting sun as being reasonably the last for him.

Almer did not attempt to go behind the note and guess who was the informer that had lodged information with the governor-general. He had forgotten, in fact, the incident of the night before, when the blustering Capper called the newly arrived Woodhouse by name. The flash of suspicion that attached responsibility to the American girl named Gerson was dissipated as quickly as it came; she had arrived by motor from Paris, not on the boat from Alexandria. His was now the imperative duty to carry warning to the two suspected, not to waste time in idle speculation as to the identity of the betrayer. There was but one ray of hope in this sudden pall of gloom, and that Almer grasped eagerly. He knew the character of General Crandall—the phlegmatic conservatism of the man, which would not easily be jarred out of an accustomed line of thought and action. The general would be slow to leap at an accusation brought against one wearing the stripes of service; and, though he might reasonably attempt to test Captain Woodhouse, one such as Woodhouse, chosen by the Wilhelmstrasse to accomplish so great a mission, would surely have the wit to parry suspicion.

Yes, he must be put on his guard. As for Louisa—well, it would be too bad if the girl should have to put her back against a wall; but she could be spared; she was not essential. After he had succeeded in getting word of his danger to Woodhouse, Almer would consider saving Louisa from a firing squad. The nimble mind of Herr Almer shook itself free from the incubus of dread and leaped to the exigency of the moment. Calling his head waiter to keep warm the chair behind the desk, Almer retired to his room, and there was exceedingly busy for half an hour.

The hour of parade during war time on Gibraltar was one o'clock. At that time, six days a week, the half of the garrison not actually in fighting position behind the great guns of the defense marched to the parade grounds down by the race track and there went through the grilling regimen that meant perfection and the maintenance of a hair-trigger state of efficiency. Down from the rocky eminences where the barracks stood, marched this day block after block of olive-drab fighting units—artillerymen for the most part, equipped with the rifle and pack of infantrymen. No blare of brass music gave the measure to their step; bandsmen in this time of reality paced two by two, stretchers carried between them. All the curl and snap of silken banners that made the parade a moving spectacle in ordinary times was absent; flags do not figure in the grim modern business of warfare. Just those solid blocks of men trained to kill, sweeping down on to the level grounds and massing, rank on rank, for inspection and the trip-hammer pound-pound-pound of evolutions to follow. Silent integers of power, flexing their muscles for the supreme test that any morning's sun might bring.

Mr. Henry J. Sherman stood with his wife, Kitty and Willy Kimball—Kimball had developed a surprising interest in one of these home folks, at least—under the shade of the row of plane trees fringing the parade grounds. They tried to persuade themselves that they were seeing something worth while. This pleasing fiction wore thin with Mr. Sherman before fifteen minutes had passed.

"Shucks, mother! The boys at the national-guard encampment down to Galesburg fair last year made a better showing than this." He pursed out his lips and regarded a passing battalion with a critical eye.

"Looked more like soldiers, anyway," mother admitted. "Those floppy, broad-brimmed hats our boys wear make them look more—more romantic, I'd say."

"But, my dear Mrs. Sherman"—Willy Kimball flicked his handkerchief from his cuff and fluttered it across his coat sleeve, where dust had fallen—"the guards back in the States are play soldiers, you know; these chaps, here—well, they are the real thing. They don't dress up like picture-book soldiers and show off——"
