The deep flush which excitement had spread over the face of Mrs. Abercrombie faded off, and the deadly pallor returned. Her hands shook so that the letter dropped out of them and fell to the floor. Another groan as of a breaking heart sobbed through her lips as she threw herself in despairing abandonment across the bed and buried her face deep among the pillows.

She needed no interpreter to unfold the true meaning of that letter. Its unsteady and blotted words and its scrawled, uncertain signature told her too well of her husband's sad condition. His old enemy had stricken him down, his old strong, implacable enemy, always armed, always lying in wait for him, and always ready for the unguarded moment.

CHAPTER XV.

DOCTOR HILLHOUSE was in his office one morning when a gentleman named Carlton, in whose family he had practiced for two or three years, came in. This was a few weeks before the party at Mr. Birtwell's.

"Doctor"—there was a troubled look on his visitor's face—"I wish you would call in to-day and examine a lump on Mrs. Carlton's neck. It's been coming for two or three months. We thought it only the swelling of a gland at first, and expected it to go away in a little while. But in the last few weeks it has grown perceptibly."

"How large is it?" inquired the doctor.

"About the size of a pigeon's egg."

"Indeed! So large?"

"Yes; and I am beginning to feel very much concerned about it."
