“ ‘Well, Sarah found that she could not make a living in Liverpool, so she went back, as I understand, to live with her sister in Croydon, and things jogged on much the same as ever at home. And then came this week and all the misery and ruin.
“ ‘It was in this way. We had gone on the May Day for a round voyage of seven days, but a hogshead got loose and started one of our plates, so that we had to put back into port for twelve hours. I left the ship and came home, thinking what a surprise it would be for my wife, and hoping that maybe she would be glad to see me so soon. The thought was in my head as I turned into my own street, and at that moment a cab passed me, and there she was, sitting by the side of Fairbairn, the two chatting and laughing, with never a thought for me as I stood watching them from the footpath.
“ ‘I tell you, and I give you my word for it, that from that moment I was not my own master, and it is all like a dim dream when I look back on it. I had been drinking hard of late, and the two things together fairly turned my brain. There’s something throbbing in my head now, like a docker’s hammer, but that morning I seemed to have all Niagara whizzing and buzzing in my ears.
“ ‘Well, I took to my heels, and I ran after the cab. I had a heavy oak stick in my hand, and I tell you I saw red from the first; but as I ran I got cunning, too, and hung back a little to see them without being seen. They pulled up soon at the railway station. There was a good crowd round the booking-office, so I got quite close to them without being seen. They took tickets for New Brighton. So did I, but I got in three carriages behind them. When we reached it they walked along the Parade, and I was never more than a hundred yards from them. At last I saw them hire a boat and start for a row, for it was a very hot day, and they thought, no doubt, that it would be cooler on the water.
“ ‘It was just as if they had been given into my hands. There was a bit of a haze, and you could not see more than a few hundred yards. I hired a boat for myself, and I pulled after them. I could see the blur of their craft, but they were going nearly as fast as I, and they must have been a long mile from the shore before I caught them up. The haze was like a curtain all round us, and there were we three in the middle of it. My God, shall I ever forget their faces when they saw who was in the boat that was closing in upon them? She screamed out. He swore like a madman and jabbed at me with an oar, for he must have seen death in my eyes. I got past it and got one in with my stick that crushed his head like an egg. I would have spared her, perhaps, for all my madness, but she threw her arms round him, crying out to him, and calling him “Alec.” I struck again, and she lay stretched beside him. I was like a wild beast then that had tasted blood. If Sarah had been there, by the Lord, she should have joined them. I pulled out my knife, and—well, there! I’ve said enough. It gave me a kind of savage joy when I thought how Sarah would feel when she had such signs as these of what her meddling had brought about. Then I tied the bodies into the boat, stove a plank, and stood by until they had sunk. I knew very well that the owner would think that they had lost their bearings in the haze, and had drifted off out to sea. I cleaned myself up, got back to land, and joined my ship without a soul having a suspicion of what had passed. That night I made up the packet for Sarah Cushing, and next day I sent it from Belfast.
“ ‘There you have the whole truth of it. You can hang me, or do what you like with me, but you cannot punish me as I have been punished already. I cannot shut my eyes but I see those two faces staring at me—staring at me as they stared when my boat broke through the haze. I killed them quick, but they are killing me slow; and if I have another night of it I shall be either mad or dead before morning. You won’t put me alone into a cell, sir? For pity’s sake don’t, and may you be treated in your day of agony as you treat me now.’
“What is the meaning of it, Watson?” said Holmes solemnly as he laid down the paper. “What object is served by
