"By Jove," he was shouting inwardly, "that poor devil was on my heels. He looked hard as he hustled past, but I stared back just as hard. It took nerve to face him. Hang it all, I'm sorry for him. He wasn't to blame. But this letter will cheer him up. It's for the kids if anything happens to him."

Apparently changing his mind at Herald Square, he instructed the driver to go down Thirty-fifth Street to Eighth Avenue and drop him at the corner. After leaving the cab he ventured into an all-night shop and bought a cheap raincoat, slouch hat and umbrella. Then, like a thief, he stole forth and warily made his way toward the dock. It was bad going and he hailed a second cab. Before climbing into it, he crossed and dropped an envelope into the mailbox.

"There," he muttered, "that helps my conscience. By Jove, this has been a corking start for the adventure. Talk about dime novels!"

He instructed the driver to take him to a point not far from the dock, a precaution which suddenly invested itself. It would be wise to approach the liner by stealth, taking no chances. They were sailing by one of the obscure lines, not for economy's sake, but to avoid possible contact with friends of their own class.

As he rattled off through the night, huddled back in the blackness of the cab, Hugh began to have the first pangs of uneasiness. The distressing fear that all had not gone well with Grace flooded his brain with misgivings and feverish doubts. A clock in a shop window told him it was nearly ten o'clock. He was cursing himself for permitting her to rush off alone in a night like this, into a quarter that reeked with uncertainty and disorder. Vague horrors presented themselves to his distressed mind; calamity stared at him from the mouth of every dark alley; outrage, crime, misfortune, danced in every shadow. As for himself, he was a sorry sight and enough to frighten Grace into convulsions at one glance. Rain-soaked, muddy, bedraggled, it was not the débonnaire Chicagoan of old who skulked away from the cab at a certain black corner and made his way stealthily, even fearfully, toward the distant dock.

Every sound startled and alarmed him; every pedestrian looked like a pursuer in plain clothes or blue. A couple of policemen eyed him sharply and he trembled in his boots. The sudden, overpowering recollection that he had the passage tickets in his pockets with the reservations and the luggage checks almost sent him flying through the air, so swift was his pace. He lost his way twice, but was set straight by unsuspecting bluecoats.

At last he zigzagged his way through devious channels and into the presence of a company's official, who informed him that Miss Ridge had not gone aboard nor had she presented herself at the dock during the evening. Hugh's jaw dropped and a sick, damp perspiration started on his forehead. Hardly knowing what he did, he went aboard and plied his questions right and left, hoping that she might have come through unobserved. But she was not there, and it was half past ten o'clock.

Out into the drizzle he sallied once more, racked by a hundred doubts and misgivings. Reproaching himself fiercely for a fool, a dolt, he posted himself at the approach to the dock and strained his eyes and ears for the first sight of Grace Vernon. Other people went aboard, but an hour passed before he gave up all hope and distractedly made up his mind to institute a search for the missing girl. He conjectured all manner of mishaps, even to the most dreadful of catastrophes. Runaway accident, robbery, abduction, even murder harassed his imagination until it became unbearable. The only cheerful alternative that he could hope for was that she might not have escaped the authorities after all and was still in custody, crushed and despairing. Reviling himself with a bitterness that was explicit but impotent, he started off resolutely to seek the aid of the police--the last extremity.

A quick little shriek came to his ears, and then the door of a cab that had been standing at the opposite corner flew open.

"Hugh! Hugh!" called a shrill voice. His heart gave a wild leap and then his long legs did the same--repeatedly. As he brought up beside the cab, Grace Vernon tumbled out, sobbing and laughing almost hysterically.
