‘Your features, and especially your eyes. Perhaps you cannot yourself recall how your reverie commenced?’

‘No, I cannot.’

‘Then I will tell you. After throwing down your paper, which was the action which drew my attention to you, you sat for half a minute with a vacant expression. Then your eyes fixed themselves upon your newly-framed picture of General Gordon, and I saw by the alteration in your face that a train of thought had been started. But it did not lead very far. Your eyes flashed across to the unframed portrait of Henry Ward Beecher which stands upon the top of your books. You then glanced up at the wall, and of course your meaning was obvious. You were thinking that if the portrait were framed, it would just cover that bare space and correspond with Gordon’s picture over there.’

‘You have followed me wonderfully!’ I exclaimed.

‘So far I could hardly have gone astray. But now your thoughts went back to Beecher, and you looked hard across as if you were studying the character in his features. Then your eyes ceased to pucker, but you continued to look across, and your face was thoughtful. You were recalling the incidents of Beecher’s career. I was well aware that you could not do this without thinking of the mission which he undertook on behalf of the North at the time of the Civil War, for I remember your expressing your passionate indignation at the way in which he was received by the more turbulent of our people. You felt so strongly about it, that I knew you could not think of Beecher without thinking of that also. When a moment later I saw your eyes wander away from the picture, I suspected that your mind had now turned to the Civil War, and when I observed that your lips set, your eyes sparkled, and your hands clenched, I was positive that you were indeed thinking of the gallantry which was shown by both sides in that desperate struggle. But then, again, your face grew sadder; your shook your head. You were dwelling upon the sadness and horror and useless waste of life. Your hand stole towards your own old wound and a smile quivered on your lips, which showed me that the ridiculous side of this method of settling international questions had forced itself upon your mind. At this point I agreed with you that it was preposterous, and was glad to find that all my deductions had been correct.’

‘Absolutely!’ said I. ‘And now that you have explained it, I confess that I am as amazed as before.’

‘It was very superficial, my dear Watson, I assure you. I should not have intruded it upon your attention had you not shown some incredulity the other day. But I have in my hands here a little problem which may prove to be more difficult of solution than my small essay in thought reading. Have you observed in the paper a short paragraph referring to the remarkable contents of a packet sent through the post to Miss Susan Cushing, of Cross Street, Croydon?’

‘No, I saw nothing.’

‘Ah! then you must have overlooked it. Just toss it over to me. Here it is, under the financial column. Perhaps you would be good enough to read it aloud.’

I picked up the paper which he had thrown back to me, and read the paragraph indicated. It was headed, ‘A Gruesome Packet.’

‘Miss Susan Cushing, living at Cross Street, Croydon, has been made the victim of what must be regarded as a peculiarly revolting practical joke, unless some more sinister meaning should prove to be attached to the incident. At two o’clock yesterday afternoon a small packet, wrapped in brown paper, was handed in by the postman. A cardboard box was inside, which was filled with coarse salt. On emptying this, Miss Cushing was horrified to find two human ears, apparently quite freshly severed. The box had been sent by parcel post from Belfast upon the morning before. There is no indication as to the sender, and the matter is the more mysterious as Miss Cushing, who is a maiden lady of fifty, has led a most retired life, and has so few acquaintances or correspondents that it is a rare event for her to receive anything through the post. Some years ago, however, when she resided at Penge, she let apartments in her
