He would have woken soon afterwards anyway even if he hadn't been disturbed, as he had had enough sleep and felt fully rested. But he had the impression that some hurried steps and the sound of the door leading into the front room being carefully shut had woken him.
Seguramente no se hubiese despertado mucho más tarde, aun sin ser molestado, porque se sentía suficientemente repuesto y descansado; sin embargo, le parecía como si le hubiesen despertado unos pasos fugaces y el ruido de la puerta que daba al vestíbulo al ser cerrada con cuidado.
