How would you interpret ‘clean’ here? It was this road that brought Mr. Shepherd to town, when his parkway ended without further ado. After driving day and night through high-mountain vistas, he would have found himself in the long tunnel through Swannanoa Gap, then spit out from darkness into the valley. He stopped at one of the large houses on the Tunnel Road that had been made a boardinghouse. That was Mrs. Bittle’s, a widow lady with children all grown who found herself betwixt the rock and the rail in ’34, so began to take in boarders. I was her first one. She had a sign made to put out in the yard whenever she had a vacancy: “Clean To Let With Meals $10 Week, Only Good People Here.” Somehow the wording of it struck Mr. Shepherd. Those words changed his course, brought his long drive to an end. How would you interpret ‘clean’ in the sentence: Clean To Let With Meals $10 Week, Only Good People Here? Thanks!
