"I am coming to be of the same opinion, Miss Cushing," said Holmes, taking a seat beside her. "I think that it is more than probable—" he paused, and I was surprised on glancing round to see that he was staring with singular intentness at the lady's profile. Surprise and satisfaction were both for an instant to be read upon his eager face, though when she glanced round to find out the cause of his silence he had become as demure as ever. I stared hard myself at her flat, grizzled hair, her trim cap, her little gilt earrings, her placid features; but I could see nothing which could account for my companion's evident excitement.
"There were one or two questions——"
"Oh, I am weary of questions!" cried Miss Cushing, impatiently.
"You have two sisters, I believe."
"How could you know that?"
"I observed the very instant that I entered the room that you have a portrait group of three ladies upon the mantelpiece, one of whom is undoubtedly yourself, while the others are so exceedingly like you that there could be no doubt of the relationship."
"Yes, you are quite right. Those are my sisters, Sarah and Mary."
"And here at my elbow is another portrait, taken at Liverpool, of your younger sister, in the company of a man who appears to be a steward by his uniform. I observe that she was unmarried at the time."
"You are very quick at observing."
"That is my trade."
