The Golden Triangle by Maurice LeBlanc

Dr. Géradec's hospital had several annexes, each of which served a specific purpose, grouped around it in a fine garden. The villa itself was used for the big operations. The doctor had his consulting-room here also; and it was to this room that Siméon Diodokis was first shown. But, after answering a few questions put to him by a male nurse, Siméon was taken to another room in a separate wing.

Here he was received by the doctor, a man of about sixty, still young in his movements, clean-shaven and wearing a glass screwed into his right eye, which contracted his features into a constant grimace. He was wrapped from the shoulders to the feet in a large white operating-apron.
