"Gunpowder!" said the detective, in a puzzled tone; "now, what possible connection can gunpowder have with this matter?"

To this there was no answer; and by the glimmer of the single match, the two men looked blankly at one another.

[CHAPTER II].

A RECOGNITION.

Topping this discovery came the return of Mrs. Boazoph with a candle and an apology. Her procedure was so exactly the same as that suggested by Fanks that Crate could not forbear from paying the tribute of an admiring chuckle to the perspicuity of his chief. Only in her action with the tablecloth did Mrs. Boazoph vary from the prescribed ritual.

"My regrets and apologies, sir," she said, addressing Fanks, with a side glance at the table; "but one of the servants--an idle slut, whom I have now discharged--turned off the gas at the meter by accident. I hope that you were not alarmed by the sudden darkness. Permit me to relight the burners."

And with this neat speech she mounted a chair with the activity of a girl. Having remedied the accident she stumbled--or seemed to stumble--in descending, and caught at the table to save herself, thereby dragging the cloth on to the floor. Then it was that Crate chuckled; whereupon Mrs. Boazoph was on her feet at once, with a look of startled suspicion. However, as she had accomplished her object, she recovered her equanimity speedily and made another apology, with a lie tacked on to it.

"My regrets for the second accident," she remarked glibly, "but it is due to overstrung nerves. Put it down to that gentleman, if you please, and you will put it down to the right cause."

"Pray do not mention it, Mrs. Boazoph," said Fanks, significantly; "I have already examined the cloth. And now, if you please, we will go upstairs."

The woman drew back and bit her lip. She guessed that Fanks had seen through her stratagem, and for the moment she was minded to excuse herself. Fortunately her habitual caution saved her from a second blunder; and she strove to conciliate Fanks by a piece of news.
