It was a cosy, well-furnished apartment, with two candles burning upon the table and two upon the mantelpiece. In the corner, stooping over a desk, there sat what appeared to be a little girl. Her face was turned away as we entered, but we could see that she was dressed in a red frock, and that she had long white gloves on. As she whisked round to us I gave a cry of surprise and horror. The face which she turned towards us was of the strangest livid tint, and the features were absolutely devoid of any expression. An instant later the mystery was explained. Holmes, with a laugh, passed his hand behind the child's ear, a mask peeled off from her countenance, and there was a little coal-black negress with all her white teeth flashing in amusement at our amazed faces. I burst out laughing out of sympathy with her merriment, but Grant Munro stood staring, with his hand clutching at his throat. [Illustration: "THERE WAS A LITTLE COAL-BLACK NEGRESS."] "My God!" he cried, "what can be the meaning of this?" "I will tell you the meaning of it," cried the lady, sweeping into the room with a proud, set face. "You have forced me against my own judgment to tell you, and now we must both make the best of it. My husband died at Atlanta. My child survived." "Your child!" She drew a large silver locket from her bosom. "You have never seen this open." "I understood that it did not open." She touched a spring, and the front hinged back. There was a portrait within of a man, strikingly handsome and intelligent, but bearing unmistakable signs upon his features of his African descent. "That is John Hebron, of Atlanta," said the lady, "and a nobler man never walked the earth. I cut myself off from my race in order to wed him; but never once while he lived did I for one instant regret it. It was our misfortune that our only child took after his people rather than mine. It is often so in such matches, and little Lucy is darker far than ever her father was. But, dark or fair, she is my own dear little girlie, and her mother's pet." The little creature ran across at the words and nestled up against the lady's dress.
