“It is all very clear. But why suspect the governess?”

“Well, in the first place there is some very direct evidence. A revolver with one discharged chamber and a calibre which corresponded with the bullet was found on the floor of her wardrobe.” His eyes fixed and he repeated in broken words, “On⁠—the⁠—floor⁠—of⁠—her⁠—wardrobe.” Then he sank into silence, and I saw that some train of thought had been set moving which I should be foolish to interrupt.

Love, fortune, power, all depending upon one middle-aged life. Ugly, Watson⁠—very ugly!”

“Yes, indeed, Holmes.”
