The White Sister by F. Marion Crawford

Sister Giovanna was the supervising nurse for the week, and in the natural course of her duty it was she who went to the telephone when Doctor Pieri called up the hospital at seven o'clock. In a few words he explained the case as far as was necessary, and begged the Sister to have a good room ready for the patient; he believed that Number Two was vacant.

It was, and the wounded man could have it. The Doctor said he would bring him in a motor towards nine o'clock.
