“We have never found it necessary.”
“You don’t keep a dog?”
“Yes, but he is chained on the other side of the house.”
“When do the servants go to bed?”
“About ten.”
“I understand that William was usually in bed also at that hour.”
“Yes.”
“It is singular that on this particular night he should have been up. Now, I should be very glad if you would have the kindness to show us over the house, Mr. Cunningham.”
A stone-flagged passage, with the kitchens branching away from it, led by a wooden staircase directly to the first floor of the house. It came out upon the landing opposite to a second more ornamental stair which came up from the front hall. Out of this landing opened the drawing-room and several bedrooms, including those of Mr. Cunningham and his son. Holmes walked slowly, taking keen note of the architecture of the house. I could tell from his expression that he was on a hot scent, and yet I could not in the least imagine in what direction his inferences were leading him.
“My good sir,” said Mr. Cunningham with some impatience, “this is surely very unnecessary. That is my room at the end of the stairs, and my son’s is the one beyond it. I leave it to your judgment whether it was possible for the thief to have come up here without disturbing us.”
