Sorrell and Son by Warwick Deeping

In the autumn of that year Kit became a student at St. Martha's Hospital, with rooms in Brunswick Square.

Sorrell had taken a share in the choice of the rooms, for provided with recommendations by the Dean of the hospital, they had explored all that region that lies between Regent's Park and Oxford Street. Kit's rooms were on the third floor, and his sitting-room overlooked the square, with the morning sun shining in, and Sorrell, remembering the days of his squalid contrivings, had liked the house and its atmosphere. It was kept by a Mrs. Gibbins, a straight up and down woman, who had been none too eager to lodge a medical student, and who had met Sorrell with an air of vague antagonism. Nor were they cheap rooms,--but rather above the level of the ordinary student's finances.
