She leaned on her elbows and smiled at me humorously.

"Would you really like to know, Signor? Well, I was an impostor." She sat with her back to the fire, and a weird halo of light seemed to surround her and frame her. "Mrs. Hyphen-Bonds accidentally dropped that invitation in my studio, a few days before she sailed for Europe.

I simply could not resist the temptation. That is all the mystery there is."

"And they still think you were there rightfully!"

"You are no longer mystified?"

"Yes; there is yet another mystery to solve: myself." I knew it.

Without rhyme or reason, I was in love; and without rhyme or reason, I was glad of it.

"Shall you ever be able to solve such a mystery?"--quizzically.

"It all depends upon you."

"Mr. Comstalk, you will not mar the exquisite humor of our adventure by causing me any annoyance. I am sure that some day we shall be very good friends. But one does not talk of love on eight hours'

acquaintance. Besides, you would be taking advantage of my helplessness; for I really depend upon you to see me safe back to New York. It is only the romance, the adventure; and such moonlight nights often superinduce sentimentality. What do you know of me? Nothing.

What do I know of you? Nothing, save that there is a kindred spirit which is always likely to lead us into trouble. Down in your heart you know you are only temporarily affected by moonshine. Come, make me a toast!"--lifting her cup.

"You are right," said I. "I am a gentleman. But it was only consistent that, having been the fool, I should now play the a.s.s.

Here's!"--and I held up my cup.

But neither of us drank; there wasn't time.

For the door opened quietly, and in walked the two men we had seen upon entering the Inn. One of them gently closed the door and locked it.

One was in soiled every-day clothes, the other in immaculate evening dress. The latter doffed his opera hat with the most engaging smile imaginable. The girl and I looked up at him in blank bewilderment, and set our cups down so mechanically that the warm amber liquid spattered on the table-cloth.

Galloping d.i.c.k and the affable inspector of the cellars stood before us!

"The unexpected always happens," began the pseudo-detective, closing his hat, drawing off his gloves and stuffing them into a pocket. "As a friend of mine used to say, it is the unexpected that always surprises us. We never expected to see these charming masqueraders again, did we, William?"

"No, sir," said William, grinning affably, "we didn't. The gentleman was very nice and obliging to me, sir, when I was in the cellars."

"So I understand. Now," continued the late Mr. Haggerty, with the deadly affability of a Macaire, "I beg of you, Mr. Comstalk, I beg of you not to move or to become unduly excited. Physicians tell us that excitement wastes the red corpuscles, that is to say, the life of the blood."

"Your blood, sir, must be very thin," I returned coolly. But I cursed him soundly in my mind. William's bulging side-pocket convinced me that any undue excitement on my part would be exceedingly dangerous.

"William, you can always tell a gentleman," said the chief rogue admiringly. "A gentleman always recognizes his opportunities, and never loses his sense of the balance of things."

"And he is usually witty, too, sir," William a.s.sented.

The girl sat pale and rigid in her chair.

"What do you want?" I demanded savagely.

"For one thing, I should like to question the propriety of a gentleman's sitting down to dine with a lady without having washed his face. The coal-dust does not add to your manly beauty. You haven't a cake of soap about you, William, have you?"

"No, sir." William's face expressed indescribable enjoyment of the scene.

The girl's mouth stiffened. She was struggling to repress the almost irresistible smile that tickled her lips.

"In times like these," said I, determined not to be outdone, "we are often thoughtless in regard to our personal appearances. I apologize to the lady."

"Fine, fine! I sincerely admire you, Mr. Comstalk. You have the true spirit of adventure. Hasn't he, William?"

"He certainly has, sir."

"Comes to a private ball without an invitation, and has a merry time of it indeed. To have the perfect sense of humor--that is what makes the world go round."

"Aren't you taking extra risk in offering me these pleasantries?" I asked.

"Risks? In what manner?"

"The man you so cleverly impersonated is at the club." I do not know what prompted me to put him on his guard.

The rogue laughed lightly. "I know Mr. Haggerty's habits. He is hustling back to New York as fast as he can. He pa.s.sed here ten minutes ago in the patrol, lickety-clip! He wishes to warn all p.a.w.nbrokers and jewelers to be on the lookout for me to-morrow. Ten thousand in a night!"--jovially.

"A _very_ tidy sum, sir," said William.

"A fourth of which goes to you, my good and faithful friend."

"Thank you, sir," replied William.

Two cooler rogues I never wish to meet!

"But wouldn't it be well, sir, to hasten?" asked William.

"We have plenty of time now, my son."

"You have not entered this room," said the girl, her terror slipping from her, "simply to offer these ba.n.a.lities. What do you wish?"

"What perspicacity, William!" cried the rogue, taking out a cigarette case.

"I don't know what that word means, sir, but as you do, it seems to fit the occasion proper enough."

"It means, William, that this charming young lady scents our visit from afar."

"I had a suspicion, sir, that it might mean that." William leaned against the wall, his beady eyes twinkling merrily.

The master rogue lighted a cigarette at one of the candles.

"Pardon me," he said, "but will you join me?"--proffering the handsome gold case.

I took a cigarette and fired it. (I really wanted it.) I would show up well before this girl if I died for it. I blew a cloud of smoke at the candle-flame. There _was_ a sparkle of admiration in the girl's eyes.
