"Well, then, after nine o'clock you shall."
"Because if she's bent on skylarking, she'll leave the house before then," laughed the other.
"And you want to be here if she goes out?"
"Well, yes, rather!"
They compromised matters by both remaining, Byrd within view of the house and Hickory on a corner within hail. Neither expected much from this effort at surveillance, there seeming to be no good reason why she should venture forth into the streets again that night. But the watchfulness of the true detective mind is unceasing.
Several hours passed. The peace of evening had come at last to the troubled town. In the streets, especially, its gentle influence was felt, and regions which had seethed all day with a restless and impatient throng were fast settling into their usual quiet and solitary condition. A new moon hung in the west, and to Mr. Byrd, pacing the walk in front of Imogene's door, it seemed as if he had never seen the town look more lovely or less like the abode of violence and crime. All was so quiet, especially in the house opposite him, he was fast becoming convinced that further precautions were needless, and that Imogene had no intention of stirring abroad again, when the window where her light burned suddenly became dark, and he perceived the street door cautiously open, and her tall, vailed figure emerge and pass rapidly up the street. Merely stopping to give the signal to Hickory, he hastened after her with rapid but cautious steps.
She went like one bound on no uncertain errand. Though many of the walks were heavily shaded, and the light of the lamps was not brilliant, she speeded on from corner to corner, threading the business streets with rapidity, and emerging upon the large and handsome avenue that led up toward the eastern district of the town before Hickory could overtake Byrd, and find sufficient breath to ask:
"Where is she bound for? Who lives up this way?"
"I don't know," answered Byrd, lowering his voice in the fear of startling her into a knowledge of their presence. "It may be she is going to Miss Tremaine's; the High School is somewhere in this direction."
