I set the idea aside as one which could be disproved or confirmed at our leisure. Then we went to the garden, as you remember, and we saw the very singular contents of the little yellow box.

"The string was of the quality which is used by sail-makers aboard ship, and at once a whiff of the sea was perceptible in our investigation. When I observed that the knot was one which is popular with sailors, that the parcel had been posted at a port, and that the male ear was pierced for an earring which is so much more common among sailors than landsmen, I was quite certain that all the actors in the tragedy were to be found among our seafaring classes.

"When I came to examine the address of the packet I observed that it was to Miss S. Cushing. Now, the oldest sister would, of course, be Miss Cushing, and although her initial was 'S' it might belong to one of the others as well. In that case we should have to commence our investigation from a fresh basis altogether. I therefore went into the house with the intention of clearing up this point. I was about to assure Miss Cushing that I was convinced that a mistake had been made when you may remember that I came suddenly to a stop. The fact was that I had just seen something which filled me with surprise and at the same time narrowed the field of our inquiry immensely.

"As a medical man, you are aware, Watson, that there is no part of the body which varies so much as the human ear. Each ear is as a rule quite distinctive and differs from all other ones. In last year's Anthropological Journal you will find two short monographs from my pen upon the subject. I had, therefore, examined the ears in the box with the eyes of an expert and had carefully noted their anatomical peculiarities. Imagine my surprise, then, when on looking at Miss Cushing I perceived that her ear corresponded exactly with the female ear which I had just inspected. The matter was entirely beyond coincidence. There was the same shortening of the pinna, the same broad curve of the upper lobe, the same convolution of the inner cartilage. In all essentials it was the same ear.

"In the first place, her sister's name was Sarah, and her address had until recently been the same, so that it was quite obvious how the mistake had occurred and for whom the packet was meant. Then we heard of this steward, married to the third sister, and learned that he had at one time been so intimate with Miss Sarah that she had actually gone up to Liverpool to be near the Browners, but a quarrel had afterwards divided them. This quarrel had put a stop to all communications for some months, so that if Browner had occasion to address a packet to Miss Sarah, he would undoubtedly have done so to her old address.

"And now the matter had begun to straighten itself out wonderfully. We had learned of the existence of this steward, an impulsive man, of strong passions—you remember that he threw up what must have been a very superior berth in order to be nearer to his wife—subject, too, to occasional fits of hard drinking. We had reason to believe that his wife had been murdered, and that a man—presumably a seafaring man—had been murdered at the same time. Jealousy, of course, at once suggests itself as the motive for the crime. And why should these proofs of the deed be sent to Miss Sarah Cushing? Probably because during her residence in Liverpool she had some hand in bringing about the events which led to the tragedy. You will observe that this line of boats call at Belfast, Dublin, and Waterford; so that, presuming that Browner had committed the deed and had embarked at once upon his steamer, the May Day, Belfast would be the first place at which he could post his terrible packet.

"A second solution was at this stage obviously possible, and although I thought it exceedingly unlikely, I was determined to elucidate it before going further. An unsuccessful lover might have killed Mr. and Mrs. Browner, and the male ear might have belonged to the husband. There were many grave objections to this theory, but it was conceivable. I therefore sent off a telegram to my friend Algar, of the Liverpool force, and asked him to find out if Mrs. Browner were at home, and if Browner had departed in the May Day. Then we went on to Wallington to visit Miss Sarah.

"I was curious, in the first place, to see how far the family ear had been reproduced in her. Then, of course, she might give us very important information, but I was not sanguine that she would.
