All the lower windows were shuttered. There was not a gleam of light anywhere as I followed the path and came to the front, where there was a grass-grown gravel sweep and iron gates in the wall. This part of the house was plain and unadorned, save for a pillared porch and steps leading down to the drive. A thick growth of ivy covered it from the ground to the first-floor windows, and after I had gently tried the heavy front door, which, as I expected, was locked, this suggested a mode of entrance. If I could climb up and get on to the roof of the porch, it might be possible to force the central bedroom window, which I could see was unshuttered. The ivy was of ancient growth, the stems thick and tough. Any schoolboy could have mounted to the top of the porch. And any boy could have pushed back the catch of the window with the blade of his pocket-knife, opened it and stepped inside. I stood in a bedroom, dark, except for a little pool of moonlight by the window. I felt curtains, and I drew them before I switched on my torch. It was an ordinary bedroom, very untidy, furnished with a suite of painted deal. There was, however, a great saucer-bath full of water, and a pair of Indian clubs. The wall was hung with photographs of football teams, and in an open drawer of the little dressing-table was a pile of gold and notes. Commonplace enough, like an undergraduate's room at Oxford, but, nevertheless, it affected me unpleasantly. It was like a sudden intimacy with something abominable, as I opened the door inch by inch, and felt for the powerful pistol in my pocket. My heart hung poised for an instant as I stepped out into a dark corridor, and then I gave a gasp, and my heart almost stopped beating. I stood at the head of broad, shallow stairs. Below was a large hall, dimly lit, and pouring up to me in a volume of sound came the melodious thunder of a piano played by a master hand! At first my knees grew weak, and I clutched the shadowy banisters to save me from falling. Constance! Who could be playing in this evil house but she! I can never forget the agonized pang of mingled joy and horror that I felt. But as I crouched and listened, the fierce emotion passed away. Whoever was playing, it was not my girl. A lost soul made that music. I glided down the stairs. Certainly the wolves had left their lair, though in what manner I could not divine. The house was inhabited by but one or two people at most. All the doors along the corridor stood open, as if the rooms had been left in a hurry. The building _felt_ deserted, empty of its usual inhabitants....
