There could be no doubt that we had reached the end of our journey. Pompey ran about and whined eagerly outside the gate, where the marks of the brougham’s wheels were still to be seen. A footpath led across to the lonely cottage. Holmes tied the dog to the hedge, and we hastened onward. My friend knocked at the little rustic door, and knocked again without response. And yet the cottage was not deserted, for a low sound came to our ears⁠—a kind of drone of misery and despair which was indescribably melancholy. Holmes paused irresolute, and then he glanced back at the road which he had just traversed. A brougham was coming down it, and there could be no mistaking those gray horses.

“By Jove, the doctor is coming back!” cried Holmes. “That settles it. We are bound to see what it means before he comes.”

He opened the door, and we stepped into the hall. The droning sound swelled louder upon our ears until it became one long, deep wail of distress. It came from upstairs. Holmes darted up, and I followed him. He pushed open a half-closed door, and we both stood appalled at the sight before us.
