An elderly man, with his pretty daughter on his arm, was passing along the street, and emerged from the gloom of the cloudy evening into the light that fell across the pavement from the window of a small shop. It was a projecting window; and on the inside were suspended a variety of watches, pinchbeck, silver, and one or two of gold, all with their faces turned from the streets, as if churlishly disinclined to inform the wayfarers what o'clock it was. Seated within the shop, sidelong to the window with his pale face bent earnestly over some delicate piece of mechanism on which was thrown the concentrated lustre of a shade lamp, appeared a young man.
