He laid hat and stick on the ground by a tree; went little way up the street, past the circle of the corner light and slipped across; moved swiftly, keeping on the grass, around to the alley, came in at the Henderson's back gate, made his way to the side steps.
There was a door here that led into an entry. There were doors to kitchen and dining-room on right and left, and the back stairs. Henry knew the house. Kitchen and dining-room were both dark now, but the lights were on in parlour and hall.
He got the screen door open without a sound and felt his way into and through the dining-room. It seemed to him that there were a great many chairs in that diningroom. His shins bumped them. They met his outspread hands. Between this room and the parlour the sliding doors were shut.
He stood a moment by these doors, wondering if Arthur V. Henderson was still sitting on the top step with his back to the front screen door. Probably. He couldn't very well move without some noise. But it would be impossible to see him out there, with the parlour light on.

And the man on the steps had only to turn his head and look in through the bay window to see piano, hat, and any one who stood near, any one, in fact, in that diagonal half of the room.

Henry glanced behind him. The sliding door had closed. There was a scuffling of feet on the steps.
