"She lived alone always, I believe?"
"Yes, sir." Then Susan hesitated. "I wonder if she had a mother?"
"Why do you wonder?"
"Well, sir, the lady who came to see Miss Loach—"
"Mrs. Herne?"
"I heard her name was Mrs. Herne, but she was as like Senora Gredos as two peas, save that she was older and had gray hair."
"Hum!" said Jennings, pondering. "Did you ever hear Senora Gredos speak of Mrs. Herne?"
"Never, sir. But Mrs. Pill—the cook of Miss Loach—said that Mrs. Herne lived at Hampstead. But she was like my old mistress. When I opened the door to her I thought she was Senora Gredos. But then the scent may have made me think that."
Jennings looked up sharply. "The scent? What do you mean?"
"Senora Gredos," explained Susan quietly, "used a very nice scent—a Japanese scent called Hikui. She used no other, and I never met any lady who did, save Mrs. Herne."
