“In organising a pursuit,” said he, “the wise pursuer will always put himself in the place of the fugitives, and seek to reason as they would probably reason. Now, what more likely than that these ladies, or their coachman, or that rascally ostler, should have thought of doubling back into France? They might naturally argue that we; should never think of pursuing them in that direction. Similarly placed, that is how I should reason, and that is the course I should adopt, making for Prussia through Lorraine. Perhaps I do their intelligences too much honour--yet, to me, it seems such an obvious course.”' La Boulaye grew cold with apprehension. Yet impassively he asked: “But what of your men who are guarding the frontiers?” “Pooh! A detour might circumvent them. The Marquise might go as far north as Roubaix or Comines, or as fair south as Rocroy, or even Charlemont. Name of a name, but it is more than likely!” he exclaimed, with sudden conviction. “What do you say, Caron?” “That you rave,” answered La Boulaye coldly. “Well, we shall see. I will despatch a message to my men, bidding them spread themselves as far north as Comiines and as far south as Charlemont. Should the fugitives have made such a detour as I suggested there will be ample time to take them.” La Boulaye still contemned the notion with a fine show of indifference, but Tardivet held to his purpose, and presently despatched the messengers as he had proposed. At that Caron felt his pulses quickening with anxiety for Mademoiselle. These astute measures must inevitably result im her capture--for was it not at Roubaix that he had bidden her await him? There was but one thing to be done, to ride out himself to meet her along the road from Soignies to Oudenarde, and to escort her into France. She should go ostensibly as his prisoner, and he was confident that not all the brigands of Captain Tardivet would suffice to take her from him. Accordingly, he announced his intention of resuming his interrupted journey, and ordered his men to saddle and make ready. Meanwhile, having taken measures to recapture the Marquise should she have doubled back into France, Charlot was now organising an expedition to scour the road to Prussia, against the possibility of her having adhered to her original intention of journeying that way. Thus he was determined to take no risks, and leave her no loophole of escape. Tardivet would have set himself at the head of the six horsemen of this expedition, but that La Boulaye interfered, and this time to some purpose. He assured the Captain that he was still far from recovered, and that to spend a day in the saddle might have the gravest of consequences for him. “If the occasion demanded it,” he concluded, “I should myself urge you to chance the matter of your health. But the occasion does not. The business is of the simplest, and your men can do as much without you as they could with you.”
