“I am not clear how you came to hear the news so early this morning.”

“I am an early riser and generally take a walk before breakfast. This morning I had hardly started when the doctor in his carriage overtook me. He told me that old Mrs. Porter had sent a boy down with an urgent message. I sprang in beside him and we drove on. When we got there we looked into that dreadful room. The candles and the fire must have burned out hours before, and they had been sitting there in the dark until dawn had broken. The doctor said Brenda must have been dead at least six hours. There were no signs of violence. She just lay across the arm of the chair with that look on her face. George and Owen were singing snatches of songs and gibbering like two great apes. Oh, it was awful to see! I couldn’t stand it, and the doctor was as white as a sheet. Indeed, he fell into a chair in a sort of faint, and we nearly had him on our hands as well.”

“Remarkable - most remarkable!” said Holmes, rising and taking his hat. “I think, perhaps, we had better go down to Tredannick Wartha without further delay. I confess that I have seldom known a case which at first sight presented a more singular problem.”

Our proceedings of that first morning did little to advance the investigation. It was marked, however, at the outset by an incident which left the most sinister impression upon my mind. The approach to the spot at which the tragedy occurred is down a narrow, winding, country lane. While we made our way along it we heard the rattle of a carriage coming towards us and stood aside to let it pass. As it drove by us I caught a glimpse through the closed window of a horribly contorted, grinning face glaring out at us. Those staring eyes and gnashing teeth flashed past us like a dreadful vision.

“My brothers!” cried Mortimer Tregennis, white to his lips. “They are taking them to Helston.”

We looked with horror after the black carriage, lumbering upon its way. Then we turned our steps towards this ill-omened house in which they had met their strange fate.

It was a large and bright dwelling, rather a villa than a cottage, with a considerable garden which was already, in that Cornish air, well filled with spring flowers. Towards this garden the window of the sitting-room fronted, and from it, according to Mortimer Tregennis, must have come that thing of evil which had by sheer horror in a single instant blasted their minds. Holmes walked slowly and thoughtfully among the flower-plots and along the path before we entered the porch. So absorbed was he in his thoughts, I remember, that he stumbled over the watering-pot, upset its contents, and deluged both our feet and the garden path. Inside the house we were met by the elderly Cornish housekeeper, Mrs. Porter, who, with the aid of a young girl, looked after the wants of the family. She readily answered all Holmes’s questions. She had heard nothing in the night. Her employers had all been in excellent spirits lately, and she had never known them more cheerful and prosperous. She had fainted with horror upon entering the room in the morning and seeing that dreadful company round the table. She had, when she recovered, thrown open the window to let the morning air in, and had run down to the lane, whence she sent a farm-lad for the doctor. The lady was on her bed upstairs if we cared to see her. It took four strong men to get the brothers into the asylum carriage. She would not herself stay in the house another day and was starting that very afternoon to rejoin her family at St. Ives.
