“Thank you,” she said quietly, and turned her face and smiled at the now steel-blue reaches of the river.

He dropped in several evenings to see her. When he was in an idealistic mood she was warmly responsive. When he was arbitrary and opinionated, she met him with chaffing and raillery, and at such times she was as elusive, as baffling, as exasperating as a sprite. On occasions when he rather insistently asked her plans and her progress in her father’s case, she evaded him and held him at bay. She felt that he admired her, but with a grudging, unwilling admiration that left his fundamental disapproval of her quite unshaken.

The more she saw of this dogmatic dreamer, this erratic man of action, the more she liked him, the more she found really admirable in him. But mixed with her admiration was an alert and pugnacious fear, so big was he, so powerful, so violently hostile to all the principles involved in her belief that the whole wide world of action should in justice lie as much open to woman to choose from as to man.

Without cessation Katherine kept eyes and mind on Blake. She searched out and pondered over the thousand possible details and ramifications his conspiracy might have. No human plan was a perfect plan. By patiently watching and studying every point there was a chance that she might discover one detail, one slip, one oversight, that would give her the key to the case.

One of the thousand possibilities was that he had an active partner in his scheme. Since no such partner was visible in the open, it was likely that his associate was a man with whom Blake wished to have seemingly no relations. Were this conjecture true, then naturally he would meet this confederate in secret. She began to think upon all possible means and places of holding secret conferences. Such a meeting might be held there in Westville in the dead of night. It might be held in any large city in which individuals might lose themselves—Indianapolis, Louisville, Cincinnati, Chicago. It might be held at any appointed spot within the radius of an automobile journey.

Katherine analyzed every possible place of this last possibility. She began to watch, as she watched other possibilities, the comings and goings of the Blake automobile. It occurred to her that, if anything were in this conjecture, the meeting would be held at night; and then, a little later, it occurred to her to make a certain regular observation. The Blake garage and the West stable stood side by side and opened into the same alley. Every evening while Blake’s car was being cleaned—if it had been in use during the day—Katherine went out to say good night to her saddle horse, and as she was on friendly terms with Blake’s man she contrived, while exchanging a word with him, to read the mileage record of the speedometer. This observation she carried on with no higher hope of anything resulting from it than from any of a score of other measures. It was merely one detail of her all-embracing vigilance.

Every night she sat on watch—the evening’s earlier half usually in the rustic summer-house in the backyard, the latter part at her bedroom window. One night after most of Westville was in bed, her long, patient vigil was rewarded by seeing the Blake automobile slip out with a single vague figure at the wheel and turn into the back streets of the town.

Hours passed, and still she sat wide-eyed at her window. It was not till raucous old muzzains of roosters raised from the watch-towers of their various coops their concatenated prophecy of the dawn, that she saw the machine return with its single passenger. The next morning, as soon as she saw Blake’s man stirring about his work, she slipped out to her stable. Watching her chance, she got a glimpse of Blake’s speedometer. Then she quickly slipped back to her room and sat there in excited thought.

The evening before the mileage had read 1437; this morning the reading was 1459. Blake, in his furtive midnight journey, had travelled twenty-two miles. If he had slipped forth to meet a secret ally, then evidently their place of meeting was half of twenty-two miles distant. Where was this rendezvous?

Almost instantly she thought of The Sycamores. That fitted the requirements exactly. It was eleven miles distant—Blake had a cabin there—the place was deserted at this season of the year. Nothing could be safer than for two men, coming in different vehicles, from different points perhaps, to meet at that retired spot at such an eyeless hour.
