"Guns?"

She stared at him. He appeared quite sane.

"I remember now I was thinking of guns when I went away," he explained. "They're interesting things to think about."

"But don't you understand that I owe you a louis? I forgot all about it. If my purse weren't empty I would repay you. Will you stay here till I can get some money from my hotel—the Hôtel de Paris?"

She spoke with some vehemence. How could the creature expect her to remain in his debt? But the creature only passed his fingers through his upstanding hair and smiled wanly.

"Please don't say anything more about it. It distresses me. The croupiers don't return the stake, as a general rule, unless you ask for it. They assume you want to back your luck. Perhaps it has won again. For goodness' sake don't bother about it—and thank you very, very much."

He bowed politely and moved a step or two away. But Zora, struck by a solution of the mystery which had not occurred to her, as one cannot grasp all the ways and customs of gaming establishments in ten minutes, rushed back to the other table. She arrived just in time to hear the croupier asking whom the louis on seventeen belonged to. The number had turned up again.

This time she brought the thirty-six louis to the stranger.

"Dear me," said he, taking the money. "It is very astonishing. But why did you trouble?"

"Because I'm a woman of common sense, I suppose."
