Woodhouse, who watched, noted only one peculiarity in Capper's conduct: The drinker nursed his stick, a plain, crook-handled malacca, with a tenderness almost maternal. It never left his hands. Once when Capper dropped it and the waiter made to prop the stick against a near-by chair, the little spy leaped to his feet and snatched the cane away with a growl. Thereafter he propped his chin on the handle, only removing this guard when he had to tip his head back for another draft of champagne.
Eleven o'clock came. Capper rose from the table and looked owlishly about him. Woodhouse quickly turned his back to the man, and was absorbed in the passing strollers. When he looked back again Capper was slowly and a little unsteadily making his way around the corner into the Cannebière. Woodhouse followed, sauntering. Capper began a dilatory exploration of the various cafés along the white street; his general course was toward the city's slums about the Quai. Woodhouse, dawdling about tree boxes and dodging into shadows by black doorways, found his quarry easy to trail. And he knew that each of Capper's sojourns in an oasis put a period to the length of the pursuit. The time for him to act drew appreciably nearer with every tipping of that restless elbow.
Midnight found them down in the reek and welter of the dives and sailors' frolic grounds. Now the trailer found his task more difficult, inasmuch as not only his quarry but he himself was marked by the wolves. Dances in smoke-wreathed rooms slackened when Capper lurched in, found a seat and ordered a drink. Women with cheeks carmined like poppies wanted to make predatory love to him; dock rats drew aside and consulted in whispers. When Capper retreated from an evil dive on the very edge of the Quai, Woodhouse, waiting by the doors, saw that he was not the only shadower. Close against the dead walls flanking the narrow pavement a slinking figure twisted and writhed after the drunkard, now spread-eagling all over the street.
Woodhouse quickened his pace on the opposite sidewalk. The street was one lined with warehouses, their closely shuttered windows the only eyes. Capper dropped his stick, laboriously halted, and started to go back for it. That instant the shadow against the walls detached itself and darted for the victim. Woodhouse leaped to the cobbles and gained Capper's side just as he dropped like a sack of rags under a blow from the dock rat's fist.
"Son of a pig! This is my meat; you clear out!" The humped black beetle of a man straddling the sprawling Capper whipped a knife from his girdle and faced Woodhouse. Quicker than light the captain's right arm shot out; a thud as of a maul on an empty wine butt, and the Apache turned a half somersault, striking the cobbles with the back of his head. Woodhouse stooped, lifted the limp Capper from the street stones, and staggered with him to the lighted avenue of the Cannebière, a block away. He hailed a late-cruising fiacre, propped Capper in the seat, and took his place beside him.
"To La Vendée, Quai de la Fraternité!" Woodhouse ordered.
The driver, wise in the ways of the city, asked no questions, but clucked to his crow bait. Woodhouse turned to make a quick examination of the unconscious man by his side. He feared a stab wound; he found nothing but a nasty cut on the head, made by brass knuckles. With the wine helping, any sort of a blow would have put Capper out, he reflected.
Woodhouse turned his back on the bundle of clothes and reached for the malacca stick. Even in his coma its owner grasped it tenaciously at midlength. Without trying to disengage the clasp, Woodhouse gripped the wood near the crook of the handle with his left Hand while with his right he applied torsion above. The crook turned on hidden threads and came off in his hand. An exploring forefinger in the exposed hollow end of the cane encountered a rolled wisp of paper. Woodhouse pocketed this, substituted in its place a thin clean sheet torn from a card-case memorandum, then screwed the crook on the stick down on the secret receptacle. By the light of a match he assured himself the paper he had taken from the cane was what he wanted.
"Larceny from the person—guilty," he murmured, with a wry smile of distaste. "But assault—unpremeditated."
The conveyance trundled down a long spit of stone and stopped by the side of a black hull, spotted with round eyes of light. The driver, scenting a tip, helped Woodhouse lift Capper to the ground and prop him against a bulkhead. A bos'n, summoned from La Vendée by the cabby's shrill whistle, heard Woodhouse's explanation with sympathy.
