He threw back his shoulders with a sudden gesture, which might have been taken for that of a man about to make a plunge, and rang the bell. The heavy wooden gate, filling all the space of the arch, was opened by a tall Numidian in house livery of white. He nodded an affirmative to Woodhouse's question, and led the way through an avenue of flaming hibiscus to a house, set far back under heavy shadow of acacias. On every hand were gardens, rank foliage shutting off this walled yard from the street and neighboring dwellings. The heavy gate closed behind the visitor with a sharp snap. One might have said that Doctor Koch lived in pretty secure isolation.
Woodhouse was shown into a small room off the main hall, by its furnishings and position evidently a waiting-room for the doctor's patients. The Numidian bowed, and disappeared. Alone, Woodhouse rose and strolled aimlessly about the room, flipped the covers of magazines on the table, picked up and hefted the bronze Buddha on the onyx mantel, noted, with a careless glance, the position of the two windows in relation to the entrance door and the folding doors, now shut, which doubtless gave on the consultation room. As he was regarding these doors they rolled back and a short thickset man, with a heavy mane of iron-gray hair and black brush of beard, stood between them. He looked at Woodhouse through thick-lensed glasses, which gave to his stare a curiously intent bent.
"My office hours are from two to four, afternoons," Doctor Koch said. He spoke in English, but his speech was burred by a slight heaviness on the aspirants, reminiscent of his mother tongue. The doctor did not ask Woodhouse to enter the consultation room, but continued standing between the folding doors, staring fixedly through his thick lenses.
"I know that, Doctor," Woodhouse began apologetically, following the physician's lead and turning his tongue to English. "But, you see, in a case like mine I have to intrude"--it was "haf" and "indrude" as Woodhouse gave these words--"because I could not be here during your office hours. You will pardon?"
Doctor Koch's eyes widened just perceptibly at the hint of a Germanic strain in his visitor's speech--just a hint quickly glossed over. But still he remained standing in his former attitude of annoyance.
