was perfectly happy, and that she no longer desired his attentions. The dog is let loose at night to prevent him from endeavoring to communicate with her. So much is fairly clear. The most serious point in the case is the disposition of the child."
"What on earth has that to do with it?" I ejaculated.
"My dear Watson, you as a medical man are continually gaining light as to the tendencies of a child by the study of the parents. Don't you see that the converse is equally valid. I have frequently gained my first real insight into the character of parents by studying their children. This child's disposition is abnormally cruel, merely for cruelty's sake, and whether he derives this from his smiling father, as I should suspect, or from his mother, it bodes evil for the poor girl who is in their power."

The group of trees, with their dark leaves shining like burnished metal in the light of the setting sun, were sufficient to mark the house even had Miss Hunter not been standing smiling on the door-step.
"Have you managed it?" asked Holmes.
A loud thudding noise came from somewhere down-stairs. "That is Mrs. Toller in the cellar," said she. "Her husband lies snoring on the kitchen rug. Here are his keys, which are the duplicates of Mr. Rucastle's."
"You have done well indeed!" cried Holmes, with enthusiasm. "Now lead the way, and we shall soon see the end of this black business."
