He stood invitingly at the entrance of a little grotto, dimly illuminated by one Chinese lantern.

“I think we will sit in the open,” said Mirabelle, and pulled out a chair.

“Excuse me.”

Instantly he was by her side, the chair arranged, a cushion found, and she sank down with a sigh of relief. It was early yet for the loungers: looking round, she saw that, but for a solitary waiter fastening his apron with one eye upon possible customers, they were alone.

“You will drinke wine . . . no? An orangeade? Good!” He beckoned the waiter and gave his order. “You must excuse me if I am a little strange. I have been in Germany for many years—except during the war, when I was in France.”

Mr. Gurther had certainly been in Germany for many years, but he had never been in France. Nor had he heard a shot fired in the war. It is true that an aerial bomb had exploded perilously near the prison at Mainz in which he was serving ten years for murder, but that represented his sole warlike experience.

“You live in the country, of course?”

“In London: I am working with Mr. Oberzohn.”

“So: he is a good fellow. A gentleman.”

She had not been very greatly impressed by the doctor’s breeding, but it was satisfying to hear a stranger speak with such heartiness of her new employer. Her mind at the moment was on Heavytree Farm: the cool parlour with its chintzes—a room, at this hour, fragrant with the night scents of flowers which came stealing through the open casement. There was a fox-terrier, Jim by name, who would be wandering disconsolately from room to room, sniffing unhappily at the hall door. A lump came up into her throat. She felt very far from home and very lonely. She wanted to get up and run back to where she had left Joan and tell her that she had changed her mind and must go back to Gloucester that night . . . she looked impatiently for the waiter. Mr. Gurther was fiddling with some straws he had taken from the glass container in the centre of the table. One end of the straws showed above the edge of the table, the others were thrust deep in the wide-necked little bottle he had in the other hand. The hollow straws held half an inch of the red powder that filled the bottle.
