Dimber's room was not, like mine, at the end of the building. It was a "front room," and its two windows opened directly over the porch upon which I stood.

I had the side door of the office in full view. He could not leave the house unseen by me.

Mr. Holtz came out to talk with me. I complained of a headache and declared my intention to remain outside until it should have passed away. We conversed for half an hour, and then, as the hands of the office clock pointed to half-past ten he left me to make his nightly round through kitchen, pantries, and dining-room, locking and barring the side door of the office before going. And still Dimber Joe read on, to all appearances oblivious of time and all things else.

A wooden bench, hard and narrow, ran along the wall just under the office window, affording a seat for loungers when the office should be overfull, and the chairs all occupied. Upon this I stretched myself, and feigned sleep, for a time that seemed interminable.

Eleven o'clock; eleven loud metalic strokes from the office time keeper.

Dimber Joe lowered the leg that had been elevated, elevated the leg that had been lowered, turned a page of his novel and read on. The man's coolness was tantalizing. I longed to forget my identity as a detective, and his as a criminal, and to spring through the window, strike the book from his hand, and challenge him to mortal combat, with dirks at close quarters, or pistols at ten paces.

Half-past eleven. Dimber Joe stretched his limbs, closed his book, yawned and arose. Whistling softly, as if not to disturb my repose, he took a small lamp from a shelf behind the office desk, lighted it leisurely and went up-stairs.

As he entered the room above, a ray of light, from his window gleamed out across the road. It rested there for, perhaps, five minutes and then disappeared.

Had Dimber Joe closed his novel to retire like an honest man?
