Arethusa by F. Marion Crawford

There was consternation in little Omobono's face the next morning when he learnt that his master had gone out during the night, and had not come home. The secretary would not believe it at first, and he went himself to Zeno's bedroom and saw that the couch had not been slept on; he could tell that easily, though it was not a bed but a narrow divan covered with a carpet; for the two leathern pillows were not disturbed, and the old dark red cloak which Zeno always used as a covering was neatly folded in its place. It had been with him through the long campaign in Greece, and he had the almost affectionate associations with it which men of action often connect with objects that have served them well in dangerous times.

Zeno had not slept at home, and he had changed his clothes before going out. Questioned by Omobono, Vito could not say with any certainty what the master had put on; in fact, he could not tell at all. All the cloth hose and doublets and tunics were in their places in the cedar wardrobes and chests of drawers, except those he had taken off, which lay on a chair. It looked, said the servant, as if the master had gone out without any clothes at all!
