“Is that Mr. Holmes, the detective?”

“Yes.”

The youth looked at us with a very penetrating and, as it seemed to me, unfriendly gaze.

“What about your other child, Mr. Ferguson?” asked Holmes. “Might we make the acquaintance of the baby?”

“Ask Mrs. Mason to bring baby down,” said Ferguson. The boy went off with a curious, shambling gait which told my surgical eyes that he was suffering from a weak spine. Presently he returned, and behind him came a tall, gaunt woman bearing in her arms a very beautiful child, dark-eyed, golden-haired, a wonderful mixture of the Saxon and the Latin. Ferguson was evidently devoted to it, for he took it into his arms and fondled it most tenderly.
