"Do you know this fellow, Mr. Hamilton?" asked the chief.

"Know him? Of course I know him," answered Teddy; "and I'll stake my last dollar on his honesty."

(Thanks, Teddy!) I began to breathe.

"But--" began the chief, seized with sudden misgivings.

"It is impossible, I tell you," interrupted Hamilton. "I know this gentleman is incapable of the theft. There is some frightful mistake.

How the d.i.c.kens did you get here, d.i.c.ky?"

And briefly I told him my story, my a.s.s's ears growing inch by inch as I went along. Hamilton didn't know whether to swear or to laugh; finally he laughed.

"If you wanted to come, why didn't you write me for an invitation?"

"I shouldn't have come to your old ball, had I been invited. It was just the idea of the lark."

"We shall have to hold him, nevertheless," said the chief, "till everything is cleared up. The girl--"

Hamilton looked at the Blue Domino.

"Madame, will you do me the honor to raise your mask?"

[Ill.u.s.tration: "Madame, will you do me the honor to raise your mask?"]

She did so; and I saw Hamilton draw in his breath. Her beauty was certainly of an exquisite pattern. He frowned anxiously.

"I never saw this young woman before," he admitted slowly.

"Ha!" cried the chief, glad to find some one culpable.

"Did you receive your invitation through the proper channels?" asked Hamilton.

"I came here to-night,"--coldly, "on the invitation of Mrs.

Hyphen-Bonds, who sailed for Europe Wednesday."

Here was an alibi that was an alibi! I was all at sea. Hamilton bowed; the chief coughed worriedly behind his hand. The girl had told me she was an impostor like myself, that her ten of hearts was as dark-stained as my own. I could not make head or tail to it. Mrs.

Hyphen-Bonds! She was a law in the land, especially in Blankshire, the larger part of which she owned. What did it all mean? And what was her idea in posing as an impostor?

The door opened again.

"The patrol has come," said the officer who entered.

"Let it wait," growled the chief. "Haggerty has evidently got us all balled up. I don't believe his fashionable thief has materialized at all; just a common crook. Well, he's got him, at any rate, and the gems."

"You have, of course, the general invitation?" said Hamilton.

"Here it is,"--and she pa.s.sed the engraved card to him.

"I beg a thousand pardons!" said Hamilton humbly. "Everything seems to have gone wrong."

"Will you guarantee this man?" asked the chief of Hamilton, nodding toward me.

"I have said so. Mr. Comstalk is very well known to me. He is a retired army officer, and to my knowledge a man with an income sufficient to put him far beyond want."

"What is your name?" asked the chief of the girl, scowling. It was quite evident he couldn't understand her actions any better than I.

"Alice Hawthorne," with an oblique glance at me.

I had been right!

"What is your occupation? I am obliged to ask these questions, Miss."

"I am a miniature painter,"--briefly,

Hamilton came forward. "Alice Hawthorne? Pardon me, but are you the artist who recently completed the miniatures of the Emperor of Germany, the Princess of Hesse, and Mrs. Hyphen-Bonds?"

"I am. I believe there is no further reason for detaining me."

"Emperor of Germany?" echoed the now bewildered chief. "Why didn't you tell all this to Mr. Haggerty?"

"I had my reasons."

Once again the door opened. A burly man in a dark business-suit entered. His face ruddy and his little grey eyes sparkled with suppressed ire. He reminded me of Vautrin, the only difference being that Vautrin was French while this man was distinctly Irish. His ma.s.sive shoulders betrayed tremendous strength. He was vastly angry about something. He went to the chief's desk and rested his hands upon it.

"You are a nice specimen for a chief of police, you are!" he began.

"And who the devil are _you_?" bawled the chief, his choler rising.

"I'll tell you who I am presently."

We all eyed him in wonder. What was going to happen now?

"Which of you gentlemen is Mr. Hamilton?" asked the new-comer gruffly.

Hamilton signified that he was the gentleman by that name.

"Some ladies at your ball have been robbed of their diamonds, I understand?"

"About ten thousand dollars' worth."

"Look here, sir," cried the chief, standing up and balling his fist, "I want you to explain yourself, and mighty quick. You can't come into my presence in this manner."

"Bah! You have just permitted the cleverest rascal in the state to slip through your b.u.t.terfingers. _I_ am Haggerty."

The chief of police sat down suddenly.
