Resolutely the girl repressed a gasp of dismay. Kirkwood stared moodily into his cup.
"These men bore me fearfully," he commented at last.
"And so," continued Brentwick, "I bethought me of a counter-stroke. It is my good fortune to have a friend whose whim it is to support a touring-car, chiefly in innocuous idleness. Accordingly I have telephoned him and commandeered the use of this machine—mechanician, too.... Though not a betting man, I am willing to risk recklessly a few pence in support of my contention, that of the two, Captain Stryker's car and ours, the latter will prove considerably the most speedy....
"In short, I suggest," he concluded, thoughtfully lacing his long white fingers, "that, avoiding the hazards of cab and railway carriage, we motor to Chiltern: the night being fine and the road, I am told, exceptionally good. Miss Dorothy, what do you think?"
Instinctively the girl looked to Kirkwood; then shifted her glance to their host. "I think you are wonderfully thoughtful and kind," she said simply.
"And you, Philip?"
"It's an inspiration," the younger man declared. "I can't think of anything better calculated to throw them off, than to distance them by motor-car. It would be always possible to trace our journey by rail."
"Then," announced Brentwick, making as if to rise, "we had best go. If neither my hearing nor Captain Stryker's car deceives me, our fiery chariot is panting at the door."
A little sobered from the confident spirit of quiet gaiety in which they had dined, they left the table. Not that, in their hearts, either greatly questioned their ultimate triumph; but they were allowing for the element of error so apt to set at naught human calculations. Calendar himself had already been proved fallible. Within the bounds of possibility, their turn to stumble might now be imminent.
When he let himself dwell upon it, their utter helplessness to give Calendar pause by commonplace methods, maddened Kirkwood. With another scoundrel it had been so simple a matter to put a period to his activities by a word to the police. But he was her father; for that reason he must continually be spared ... Even though, in desperate extremity, she should give consent to the arrest of the adventurers, retaliation would follow, swift and sure. For they might not overlook nor gloze the fact that hers had been the hands responsible for the theft of the jewels; innocent though she had been in committing that larceny, a cat's-paw guided by an intelligence unscrupulous and malign, the law would not hold her guiltless were she once brought within its cognizance. Nor, possibly, would the Hallams, mother and son.
