Utterly bewildered, the young man walked on without thought of direction, and rambled dreamily about the streets for an hour or two. He could not make up his mind whether or not to fulfil the promise of calling to see Miss Madeley to-morrow morning. At one moment he regretted having taken lodgings in Gower Place; at another he determined to make use of his advantage, and play the spy upon Eve's movements without scruple. The interest she had hitherto excited in him was faint indeed compared with emotions such as this first glimpse of her had kindled and fanned. A sense of peril warned him to hold aloof; tumult of his senses rendered the warning useless. At eleven o'clock he was sitting by his bedroom window, in darkness, watching the house across the way. CHAPTER VI It was just upon midnight when Eve returned. She came at a quick walk, and alone; the light of the street-lamps showed her figure distinctly enough to leave the watcher in no doubt. A latchkey admitted her to the house. Presently there appeared a light at an upper window, and a shadow kept moving across the blind. When the light was extinguished Hilliard went to bed, but that night he slept little. The next morning passed in restless debate with himself. He did not cross the way to call upon Eve: the thought of speaking with her on the doorstep of a lodging-house proved intolerable. All day long he kept his post of observation. Other persons he saw leave and enter the house, but Miss Madeley did not come forth. That he could have missed her seemed impossible, for even while eating his meals he remained by the window. Perchance she had left home very early in the morning, but it was unlikely. Through the afternoon it rained: the gloomy sky intensified his fatigue and despondence. About six o'clock, exhausted in mind and body, he had allowed his attention to stray, when the sudden clang of a street organ startled him. His eyes turned in the wonted direction--and instantly he sprang up. To clutch his hat, to rush from the room and from the house, occupied but a moment. There, walking away on the other side, was Eve. Her fawn-coloured mantle, her hat with the yellow flowers, were the same as yesterday. The rain had ceased; in the western sky appeared promise of a fair evening. Hilliard pursued her in a parallel line. At the top of the street she crossed towards him; he let her pass by and followed closely. She entered the booking-office of Gower Street station; he drew as near as possible and heard her ask for a ticket-- "Healtheries; third return." The slang term for the Health Exhibition at Kensington was familiar to him from the English papers he had seen in Paris. As soon as Eve had passed on he obtained a like ticket and hastened down the steps in pursuit. A minute or two and he was sitting face to face with her in the railway carriage.
