Abruptly he caught the girl by the arm and unceremoniously hurried her toward a waiting hansom.

"Quick!" he begged her. "Jump right in—not an instant to spare.—"

She nodded brightly, lips firm with courage, eyes shining.

"My father?"

"Yes." Kirkwood glanced back over his shoulder. "He hasn't seen us yet. They've just driven up. Stryker's with him. They're getting down." And to himself, "Oh, the devil!" cried the panic-stricken young man.

He drew back to let the girl precede him into the cab; at the same time he kept an eye on Calendar, whose conveyance stood half the length of the station-front away.

The fat adventurer had finished paying off the driver, standing on the deck of the hansom. Stryker was already out, towering above the mass of people, and glaring about him with his hawk-keen vision. Calendar had started to alight, his foot was leaving the step when Stryker's glance singled out their quarry. Instantly he turned and spoke to his confederate. Calendar wheeled like a flash, peering eagerly in the direction indicated by the captain's index finger, then, snapping instructions to his driver, threw himself heavily back on the seat. Stryker, awkward on his land-legs, stumbled and fell in an ill-calculated attempt to hoist himself hastily back into the vehicle.

To the delay thus occasioned alone Kirkwood and Dorothy owed a respite of freedom. Their hansom was already swinging down toward the great gates of the yard, the American standing to make the driver comprehend the necessity for using the utmost speed in reaching the Craven Street address. The man proved both intelligent and obliging; Kirkwood had barely time to drop down beside the girl, ere the cab was swinging out into the Strand, to the peril of the toes belonging to a number of righteously indignant pedestrians.

"Good boy!" commented Kirkwood cheerfully. "That's the greatest comfort of all London, the surprising intellectual strength the average cabby displays when you promise him a tip.... Great Heavens!" he cried, reading the girl's dismayed expression. "A tip! I never thought—!" His face lengthened dismally, his eyebrows working awry. "Now we are in for it!"

Dorothy said nothing.
