"With such an inducement nothing can prevent me from reaching Buffalo tomorrow," said Grant. "Bye-bye, then, until we meet there," answered Dixie and turned to re-enter the hotel. A few moments later she had rejoined Heinric von Lertz in the dining room and was assuring him that the massage which he had suggested had all but vanquished her headache. Eagerly he extended an invitation to a matinee, dinner and then an auto ride to the railroad station in Jersey for the train to Buffalo, and was boyishly pleased when she accepted. Excusing himself, he telephoned brusque orders to Baroness Verbecht and Madam Stephan to join him at the train and then rejoined Dixie for the round of pleasure he had planned. Arriving in Buffalo the party was driven to the Algonquin Hotel. As they paused at the desk for Von Lertz to register, a bellboy hurried up to Dixie. "You dropped this, Miss," he asserted. "Oh, I thank you," responded Dixie, accepting a dainty lace handkerchief she had never seen before, when she caught a significant gleam in the young man's eyes. The bellboy turned away quickly to accept, nonchalantly, a tip which Von Lertz had extended. Without attracting the attention of the rest of her party, Dixie found an opportunity to stretch the handkerchief out. On the small piece of linen in the centre was written in pencil: "Bearer of this will be constantly with me, and will keep careful watch for any messages from you. H.G." "A trip to the Welland Canal is really nice in an auto." It was the voice of Von Lertz which broke in upon the pleasant musings which the message had aroused. "If that is intended for an invitation, there is nothing I would like better," responded Dixie quickly. "Will the Baroness and Madame accompany us?" "They must remain here, for their work may begin any time," returned the spy and then escorted Dixie to a little roadster which he had procured. There was but little conversation on the drive out. At the canal Von Lertz drove to three of the locks and carefully surveyed the surrounding land. As the inspection progressed his spirits rose rapidly. "Good, good," he chuckled, half to Dixie and half to himself, "Koenig certainly knew what he was doing in selecting the men for this job." On the return trip he chatted gaily, and seemed to be in no hurry to get back to the hotel, keeping the speed of the car well down to the road limit. Despite this, just as they entered the boundaries of Buffalo, a heavily goggled motorcycle policeman, blocked the road. "Ten miles an hour's the limit on this road," he announced gruffly and Von Lertz brought the car to a surprised stop. "Ten miles an hour?" demanded the angered spy, "why there isn't a car built that can stand that sort of a snail's pace."
