"Pratt, you have deceived me," Colville breaks out sternly; "all your restoratives have failed, all your potent art is at fault. Look at that marble face, those breathless lips. It is death, not life, we look upon."

"Bah!" said Doctor Pratt. Rising and going to the young lady's head, he gently turned it on one side: at the same time he changed the position of one arm. Both retained for a short time their new position then slowly resumed their former place. He raised her eyelids and they remained open a brief interval, then gently closed again. The beautiful blue eyes they disclosed were neither glassy nor corpse-like, though fixed in a vacant, unnatural stare. The physician resumed his seat and said, calmly:

"You see, Colville, it is life, not death. I tell you it is that rare, mysterious affection we call catalepsy—a state fearfully blending the conditions of life and death—a seeming life in death, or death in life. It is true that all my remedies have failed: but it is equally true that life is not extinct, though the spark may perish from exhaustion if she does not soon revive. It is now four days since the cold steel entered her side and this mysterious unconsciousness fell upon her. But the horrid spell must soon be broken, or death will ensue as a consequence of loss of blood and vitality."

They withdrew a little further from the bed, Pratt still keeping a watchful eye upon the patient, while Colville tried to keep his roving glance away from the death-like face that sent a shudder of fear now and then along his frame. It seemed fearfully like death despite the learned theory of the case which Doctor Pratt was patiently explaining to him.

"You said the first time we talked of this that you believed Miss Lawrence had been murdered," said Colville, suddenly. "Why did you form that opinion despite the contrary evidence?"

"There was no evidence to the contrary," said the dark physician, complacently. "I formed it on the evidence of my own eyes. True, Miss Lawrence's door was locked on the inside; but"—he paused a moment to give effect to his words—"but a heavy, luxuriant honeysuckle vine was trained from the ground up to her window in the second story. The murderer, or murderess, entered her room by the door, turned the key, perpetrated the dreadful deed, and escaped by sliding down the thickly-twisted vine to the ground."

"That is only your theory, doctor, I suppose."

"It is a fact, not theory, monsieur. I furtively examined the vine myself. It was broken in places, bruised in its tender parts, and quantities of leaves and flowers were strewn upon the ground. It plainly showed that a heavy body had slid down upon it and injured it. I wonder that it escaped the dull eyes of the jury."

"You are an astute man, doctor. Who, then, was the assassin of one so young and fair?"

"I do not know, but I half suspected the beautiful woman who lives at Lawrence's—a sort of cousin, I think—a Mrs. Vance by name. Her evidence went a little further than the rest. She asserted that she heard the young lady lock her door that night—she seemed to favor the idea of suicide also by pressing a theory of her own, that Miss Lawrence had a secret trouble—was subject to fits of abstraction and depression. Yes, decidedly, I suspect the beautiful widow."
