Key passages
“We will suppose that there was a guilty secret, a really shameful secret in the life of this man Douglas. This leads to his murder by someone who is, we will suppose, an avenger, someone from outside.”
Holmes suggests that Douglas had a hidden shameful past, and that an outsider killed him as an act of vengeance.
Holmes outlines his alternative theory of the crime to Watson.
“In an instant—but it was just one instant too late—they resumed their solemn masks as my figure came into view.”
Mrs. Douglas and Barker quickly stopped laughing and put on serious expressions when they saw Watson approaching.
Watson catches the pair in a moment of levity, deepening his suspicion.
