A vague thrill ran through me as I listened to my companion’s words and saw the stern gravity which had hardened his features. This brutal preliminary seemed to shadow forth some strange and inexplicable horror in the background. Lestrade, however, shook his head like a man who is only half convinced.

“There are objections to the joke theory, no doubt,” said he, “but there are much stronger reasons against the other. We know that this woman has led a most quiet and respectable life at Penge and here for the last twenty years. She has hardly been away from her home for a day during that time. Why on earth, then, should any criminal send her the proofs of his guilt, especially as, unless she is a most consummate actress, she understands quite as little of the matter as we do?”

“That is the problem which we have to solve,” Holmes answered, “and for my part I shall set about it by presuming that my reasoning is correct, and that a double murder has been committed. One of these ears is a woman’s, small, finely formed, and pierced for an earring. The other is a man’s, sun-burned, discoloured, and also pierced for an earring. These two people are presumably dead, or we should have heard their story before now. To-day is Friday. The packet was posted on Thursday morning. The tragedy, then, occurred on Wednesday or Tuesday, or earlier. If the two people were murdered, who but their murderer would have sent this sign of his work to Miss Cushing? We may take it that the sender of the packet is the man whom we want. But he must have some strong reason for sending Miss Cushing this packet. What reason then? It must have been to tell her that the deed was done! or to pain her, perhaps. But in that case she knows who it is. Does she know? I doubt it. If she knew, why should she call the police in? She might have buried the ears, and no one would have been the wiser. That is what she would have done if she had wished to shield the criminal. But if she does not wish to shield him she would give his name. There is a tangle here which needs straightening out.” He had been talking in a high, quick voice, staring blankly up over the garden fence, but now he sprang briskly to his feet and walked towards the house.

“I have a few questions to ask Miss Cushing,” said he.

“In that case I may leave you here,” said Lestrade, “for I have another small business on hand. I think that I have nothing further to learn from Miss Cushing. You will find me at the police-station.”

“We shall look in on our way to the train,” answered Holmes. A moment later he and I were back in the front room, where the impassive lady was still quietly working away at her antimacassar. She put it down on her lap as we entered and looked at us with her frank, searching blue eyes.

“I am convinced, sir,” she said, “that this matter is a mistake, and that the parcel was never meant for me at all. I have said this several times to the gentleman from Scotland Yard, but he simply laughs at me. I have not an enemy in the world, as far as I know, so why should anyone play me such a trick?”

“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- -”
