am Lord Somerset Campbell, if you care to know."

"Really? Oh, well, that's all right. I'm the Duke of Argyll, so we must
be relatives. Blood is thicker than water, Campbell. Confess. Whom have
you murdered?"

"I knew," said his lordship, slowly, "that the largest lunatic asylum
in the Tyrol is near here, but I was not aware that the patients were
allowed to stroll in the Kurpark."

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

"Campbell, if you please."

"I don't please, as it happens. This masquerade has gone on long
enough. What's your crime? Or are you on the other side of the fence?
Are you practising the detective business?"

"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.

"Then you _are_ Johnson!" I cried, with some exultation.

"I thought you weren't very sure," began Johnson. "However, it doesn't
matter, but you should be above threatening a man. That was playing it
low down."

"I see you're from Chicago. Go on."

"It's all on account of this accursed visitors' tax. That I decline to
pay. I stay just under the week at a hotel, and then take a 'bus to the
station, and another 'bus to another hotel. Of course my mistake was
getting acquainted with you. I never suspected you were going to stay
here a month."

"But why didn't you let me know? Your misdemeanor is one I thoroughly
sympathize with. I wouldn't have said anything."

Johnson shook his head.

"I took a fellow into my confidence once before. He told it as a dead
secret to a friend, and the friend thought it a good joke, and related
it, always under oath that it should go no further. The authorities had
me arrested before the week was out, and fined me heavily besides
exacting the tax."

"But doesn't the 'bus fares, the changing, and all that amount to as
much as the tax?"

"I suppose it does. It isn't the money I object to, it's the principle
of the thing."
