County Street was as he had known it on every warm summer night since he was a boy, and yet conveyed that impression which every summer night conveys, of being the first and only one of its kind. The sky was majestically high and clear and spangled, with the Scorpion and the red light of Antares well above the city's amber glow. Along the streets and lanes dim trees rustled faintly, casting gigantic trembling shadows in the circles of the electric lights. The breeze being from the east and south, the tang of sea-salt mingled with the strong, dry scent of new-mown hay and the blended perfumes of a countryside of gardens. All doors were open as he passed along, and so were all windows. On all verandas and porches and steps faint figures could be discerned, low-voiced for the most part, but sending out an occasional laugh or snatch of song. Thor knew who the people were; many of them were friends; to some of them he was related; there were few with whom he hadn't ties antedating birth. It was soothing to him, as he slipped along in the heavy shadow of the elms, to know that they were near.
On approaching his father's house, which he expected to find dark, he was astonished to see a light. It was a light like a blurred star, on one of the upper floors. From what window it shone he found it difficult to say, the mass of the house being lost in the general obscurity. The strange thing was that it should be there.
He passed slowly within the gate and along the few yards of the driveway, pausing from time to time in order to place the quiet beacon in this room or in that, according to the angle from which it seemed to burn. He was not alarmed; he was only curious. It was no furtive light. Though the curtains were closed, it displayed itself boldly in the eyes of the neighbors and of the two or three ornamental constables who made their infrequent rounds in County Street. He could only attribute it to old Maggs, who lived in the coachman's cottage at the far end of the property, though as to what old Maggs could be doing in the house at this hour in the evening, at a time when the parents were abroad and Claude away on a holiday, he was obliged to be frankly inquisitive. An investigating spirit was further aroused by the fact that in one of his pauses, as he alternately advanced and halted, he was sure he heard a footstep. If it was not a footstep, it was a stirring in the shrubbery, as if something had either moved away or settled into hiding.
He was still unalarmed. Night-crimes were rare in the village, and relatively harmless even when they were committed. The sound he had heard might have been made by some roving dog, or by a cat or a startled bird. Had it not been for the light he would scarcely have noticed it. Taken in conjunction with the light, it suggested some one who had been watching and had slunk away; but even that thought was slightly melodramatic in so well-ordered a community. He went on till he was at the foot of the steps, at a point where he could no longer descry the glow in the upper window, but could perceive through the fanlight over the inner door that, though the lower hall was dark, the electrics were burning somewhere in the interior of the house.
He verified this on mounting the steps and peering into the vestibule through the strip of window at the sides of the outer door. Turning the knob tentatively, he was surprised to find it yield. On entering, he stood in the porch and listened, but no sound reached him from within. Taking his bunch of keys from his pocket, he detached his latch-key softly, and as softly inserted it in the lock. The door opened noiselessly, showing a light down the stairway from the hall above. He could now hear some one moving, probably on the topmost floor, with an opening and shutting of doors that might have been those of closets, followed by a swishing sound like that of the folding or packing of clothes. He entered and closed the door with a distinctly audible bang.
Listening again, he found that the sounds ceased suspiciously. Whoever was there was listening, too. It was easy, by the light streaming from above, to find the button and turn on the electricity in the lower hall, whereupon the movement up-stairs began again. Some one came out of a room and peered downward. He himself went to the foot of the stairs, looking up. When the watcher on the third floor spoke at last it was in a voice he didn't instantly recognize. He would have taken it for Claude's, only that it was so frightened and shrill.
"Who's there?"
"Who are you?" Thor demanded, in tones that rolled and echoed through the house.
There was a long, hesitating silence. Straining his eyes upward, Thor could dimly make out a white face leaning over the highest banister. When the question came at last it was as if reluctantly and shrinkingly.
