The day was warm. I threw up some of the windows and the boys and I played ball, using a rolled handkerchief. My part, being to sit on the floor with a newspaper folded into a bat and to bang at the handkerchief as it flew past me, became automatic after a time. As I look back I see a pair of disordered young rascals in Russian blouses and bare round knees doing a great deal of yelling and some very crooked throwing; a nurse sitting tailor fashion on the floor, alternately ducking to save her cap and making vigorous but ineffectual passes at the ball with her newspaper bat. And I see sunshine in the room and the dwarf parrot eating sugar out of his claw. And below, the fish in the aquarium floating belly-up with dull eyes. Mr. Reed brought up our luncheon tray. He looked tired and depressed and avoided my eyes. I watched him while I spread the bread and butter for the children. He nailed shut the windows that opened on to the porte-cochère roof and when he thought I was not looking he examined the registers in the wall to see if the gratings were closed. The boys put the dead fish in a box and made him promise a decent interment in the garden. They called on me for an epitaph, and I scrawled on top of the box: _These fish are dead Because a boy called Fred Went out on a porch roof when he should Have been in bed._ I was much pleased with it. It seemed to me that an epitaph, which can do no good to the departed, should at least convey a moral. But to my horror Freddie broke into loud wails and would not be comforted. It was three o’clock, therefore, before they were both settled for their afternoon naps and I was free. I had determined to do one thing, and to do it in daylight—to examine the back staircase inch by inch. I knew I would be courting discovery, but the thing had to be done, and no power on earth would have made me essay such an investigation after dark. It was all well enough for me to say to myself that there was a natural explanation; that this had been a human head, of a certainty; that something living and not spectral had slid over my foot in the darkness. I would not have gone back there again at night for youth, love or money. But I did not investigate the staircase that day, after all. I made a curious discovery after the boys had settled down in their small white beds. A venturesome fly had sailed in through an open window, and I was immediately in pursuit of him with my paper bat. Driven from the cornice to the chandelier, harried here, swatted there, finally he took refuge inside the furnace register.
