in the Tyrol is near here, but I was not aware that the patients were

"That's all very well, Johnson, but----"

"Campbell, if you please."

"I don't please, as it happens. This masquerade has gone on long

"My dear fellow, I don't know you, and I resent your impertinent
curiosity. Allow me to wish you good-day."

"It won't do, Johnson, it has gone too far. You have played on my
feelings, and I won't stand it. I'll go to the authorities and relate
the circumstances. They are just suspicious enough to----"

"Which? The authorities or the circumstances?" asked Johnson, sitting
down again.

"Both, my dear boy, both, and you know it. Now, Johnson, make a clean
breast of it, I won't give you away."

Johnson sighed, and his glass dropped from his eye. He looked around
cautiously. "Sit down," he said.
