Mrs. Croydon looked from the Count to Mrs. Neligage with an expression of mingled doubt and bewilderment. Her attitude of expecting to be received as the anonymous author vanished in an instant, and vexation began to predominate over the other emotions visible in her face.

"Well," she said spitefully, "it is certainly a day of wonders; but if the letter belongs to the Count, it would be interesting to know who writes to him as Christopher Calumus."

Mrs. Harbinger answered her in a tone so cold that Mrs. Croydon colored under it.

"Really, Mrs. Croydon," she said, "the question is a little pointed."

"Why, it is only a question about a person who doesn't exist. There isn't any such person as Christopher Calumus. I'm sure I'd like to know who writes to literary men under their assumed names."

May was so pale that only the fact that everybody was looking at Mrs. Harbinger could shield her from discovery. The hostess drew herself up with a haughty lifting of the head.

"If it is of so great importance to you," she said, "it is I who wrote the letter. Who else should write letters in this house?"

She extended her hand to the Count as she spoke, as if to recover the harmless-looking little white missive which was causing so much commotion, but the Count did not offer to return it. Tom Harbinger stood a second as if amazement had struck him dumb. Then with the air of a puppet pronouncing words by machinery he ejaculated:—

"You wrote to the Count?"

His wife turned to him with a start, and opened her lips, but before she could speak a fresh interruption prevented. Barnstable in the few moments during which he had been in the room had met with so many strange experiences that he might well be bewildered. He had been greeted by May as one for whom she was waiting, and then had been hailed as the author of the book which he hated; the eccentric Graham had made of him a sort of involuntary penny-post; he had been in the midst of a group whisking a letter about like folk in the last act of a comedy; and now here was the announcement that the Count was the anonymous libeler for whom he had been seeking. He dashed forward, every fold of his chins quivering, his hair bristling, his little eyes red with excitement. He shook his fist in the face of the Count in a manner not often seen in a polite drawing-room.
