"I say, Governor, of course this is very handsome of you, but I didn't come to tell what I know for gold. I'm a loyal Englishman, and I've done what I have for the good of the old flag."

"Quite right, Mr. Capper; quite right. But you will please accept this little gift as an inadequate recognition of your loyalty. Your name shall be mentioned in my despatches home."

Capper rehearsed this hypothetical dialogue with relish. He could even catch the involuntary gasp of astonishment from the governor when that responsible officer in his majesty's service heard the words Capper would whisper to him; could see the commander of the Rock open a drawer in his desk and take therefrom a thick white sheaf of bank-notes—count them! Then—ah, then—the first train for Paris and the delights of Paris at war-time prices.

The little spy anticipated no difficulty in gaining audience with the governor. Before he had been fifteen minutes off the Princess Mary he had heard the name of the present incumbent of Government House. Crandall—Sir George Crandall; the same who had been in command of the forts at Rangoon back in '99. Oh, yes, Capper knew him, and he made no doubt that, if properly reminded of a certain bit of work Billy Capper had done back in the Burmese city, Sir George would recall him—and with every reason for gratefulness. To-morrow—yes, before ever Sir George had had his morning's peg, Capper would present himself at Government House and tell about that house on Queen's Terrace at Ramleh; about the unconscious British officer who was carried there and hurried thence by night, and the tall well-knit man in conference with Doctor Koch who was now come to be a part of the garrison of the Rock under the stolen name of Woodhouse.

Capper had his dinner, then strolled around the town to see the sights and hear what he could hear. Listening was a passion with him.

For the color and the exotic savor of Gibraltar on a hot August night Capper had no eye. The knife edge of a moon slicing the battlements of the old Moorish Castle up on the heights; the minor tinkle of a guitar sounding from a vine-curtained balcony; a Riffian muleteer's singsong review of his fractious beast's degraded ancestry—not for these incidentals did the practical mind under the battered Capper bowler have room. Rather the scraps of information and gossip passed from one blue-coated artilleryman off duty, to another over a mug of ale, or the confidence of a sloe-eyed dancer to the guitar player in a tavern; this was meat for Capper. Carefully he husbanded his gold piece, and judiciously he spent his silver for drink. He enjoyed himself in the ascetic spirit of a monk in a fast, believing that the morrow would bring champagne in place of the thin wine his pitiful silver could command.

Then, of a sudden, he caught a glimpse of Louisa—Louisa of the Wilhelmstrasse. Capper's heart skipped, and an involuntary impulse crooked his fingers into claws.

The girl was just coming out of a café—the only café aspiring to Parisian smartness Gibraltar boasts. Her head was bare. Under an arm she had tucked a stack of cigar boxes. Had it not been that a steady light from an overhead arc cut her features out of the soft shadow with the fineness of a diamond-pointed tool, Capper would have sworn his eyes were playing him tricks. But Louisa's features were unmistakable, whether in the Lucullian surroundings of a Berlin summer garden or here on a street in Gibraltar. Capper had instinctively crushed himself against the nearest wall on seeing the girl; the crowd had come between himself and her, and she had not seen him.

All the weasel instinct of the man came instantly to the fore that second of recognition, and the glint in his eyes and baring of his teeth were flashed from brute instinct—the instinct of the night-prowling meat hunter. All the vicious hate which the soul of Billy Capper could distil flooded to his eyes and made them venomous. Slinking, dodging, covering, he followed the girl with the cigar boxes. She entered several dance-halls, offered her wares at the door of a cheap hotel. For more than an hour Capper shadowed her through the twisting streets of the old Spanish town. Finally she turned into a narrow lane, climbed flagstone steps, set the width of the lane, to a house under the scarp of a cliff, and let herself in at the street door. Capper, following to the door as quickly as he dared, found it locked.

The little spy was choking with a lust to kill; his whole body trembled under the pulse of a murderous passion. He had found Louisa—the girl who had sold him out—and for her private ends, Capper made no doubt of that. Some day he had hoped to run her down, and with his fingers about her soft throat to tell her how dangerous it was to trick Billy Capper. But to have her flung across his path this way when anger was still at white heat in him—this was luck! He'd see this Louisa and have a little powwow with her even if he had to break his way into the house.
