"You must speak," he cried. "I have paltered long enough with this matter. You must tell me what it is that is destroying your happiness and mine."

But her eyes, turning toward him, seemed to echo that must in a look of disdain eloquent enough to scorn all help from words, and in the indomitable determination of her whole aspect he saw that he might slay her, but that he could never make her speak.

Loosing her with a gesture of despair, he turned away. When he glanced back again she was gone.

The result of this interview was naturally an increased doubt and anxiety on his part. He could not attend to his duties with any degree of precision, he was so haunted by uneasy surmises as to what might have been the contents of the letter which he had thus seen her destroy before his eyes. As for her words, they were like her conduct, an insolvable mystery, for which he had no key.

His failure to find her at home when he returned that night added to his alarm, especially as he remembered the vivid thunderstorm that had deluged the town in the afternoon. Nor, though she came in very soon and offered both excuses and explanations for her absence, did he experience any appreciable relief, or feel at all satisfied that he was not threatened with some secret and terrible catastrophe. Indeed, the air of vivid and feverish excitement which pervaded every look of hers from this time, making each morning and evening distinctive in his memory as a season of fresh fear and renewed suspense, was enough of itself to arouse this sense of an unknown, but surely approaching, danger. He saw she was on the look out for some event, he knew not what, and studied the papers as sedulously as she, in the hope of coming upon some revelation that should lay bare the secret of this new condition of hers. At last he thought he had found it. Coming home one day from the court, he called her into his presence, and, without pause or preamble, exclaimed, with almost cruel abruptness:

"An event of possible interest to you has just taken place. The murderer of Mrs. Clemmens has just cut his throat."

He saw before he had finished the first clause that he had struck at the very citadel of her terrors and her woe. At the end of the second sentence he knew, beyond all doubt now, what it was she had been fearing, if not expecting. Yet she said not a word, and by no movement betrayed that the steel had gone through and through her heart.

A demon—the maddening demon of jealousy—gripped him for the first time with relentless force.

"Ah, you have been looking for it?" he cried in a choked voice. "You know this man, then—knew him, perhaps, before the murder of Mrs. Clemmens; knew him, and—and, perhaps, loved him?"

She did not reply.
