For it was undoubtedly Miss Ling's quiet-mannered first-floor lodger, who had resigned his post of teacher at the Berners Street Institute of Languages when the wire had come from Headquarters, bidding him come back and be a cog-wheel in Moltke's big war-machine. What Mr. Knewbit would have called "the blank expression" appeared behind his spectacles when they showed him his young fellow-lodger from Coram Street. But he paused when the Commandant halted and began to ask questions—which Carolan answered in the German so frequently tested on Herr von Rosius.

"How came you to travel from Berlin in a train set apart for the use of the Guard Infantry? Show me your Legitimations-Kart and military ticket, if you have one!—You have neither? ... Then how did you, against the regulations, obtain permission of the authorities to enter a militär-zug? It is inconceivable that you should have managed to conceal yourself without connivance of some kind!"

Things were getting close to the Chancellory half-sheet, but it would never be displayed with the consent of P. C. Breagh. He had wild ideas of feigning idiocy, of appealing to Von Rosius, but the first resource savored of the theater too strongly for adoption, and the second—one glance at the hard, ignoring eyes behind the steel-rimmed glasses disposed of that for good.

At his wits' end, a loud, genial voice hailed him in the English language, flavored with the County Dublin brogue.

"By the powers! and there's the face I'm looking for. Longer by a yard than it was when you capped me at Berlin. Faith! and I stared at you with all my eyes, wondering where in the world I'd last beheld ye? Till Chris Brotherton quizzed me and I bet him five shillings the place was Fleet Street. Now, on your honor, was it? Speak, or forever after hold your tongue!"

"Not quite Fleet Street, sir, but hardly a stone's throw from it!" A great wave of unreasonable hope lifted the sinking heart of P. C. Breagh.

The big, warm voice and the kind, bright glance that had wrought the miracle, belonged to a stout little bearded gentleman of fifty, topped with a hard gray Derby, and attired in a pepper-and-salt cutaway coat, brown holland vest and neat white hunting-stock, gray Bedford cords and shiny black spurred Blucher boots. Had you met him cantering on some plump and well-fed cob along a green lane in the Mother Country, you would have taken him—but for the revolver-pouch that depended from a neat black leather belt, and the wallet that, with its companioning field-glass, was slung across his shoulders—for a hard-riding country surgeon or solicitor, of the good old English kind. But P. C. Breagh knew better, and his drab world changed to rose-color, as the big voice rolled from the capacious chest:

"Hardly a minute's ... Hold on! For the life of you, don't refresh my memory! What would it be to find one's mental legs getting shaky at the start of a new campaign! Not a stone's throw from Fleet Street, did you say? ... By the Beadle of Old Trinity! if you don't mean the Maze at Hampton Court or the Nevski Prospect at Petersburg, or the garden of the Dilkusha at Lucknow, you're talking of Printing House Square! Am I right now?"

"You've hit the nail, sir! You were walking arm-in-arm with Mr. Sala—and I'd been introduced to him before, luckily! and he remembered my name and presented me to you!"

"And I'm five shillings the richer by the meeting. For if Chris Brotherton dares to say the Thunderbolt office and Fleet Street are anything but synonymous, he's a bolder man than I take him to be. But I'm interrupting a conversation...." He broke off, saluting the official. "Pray accept my apologies, Herr Commandant, I'll wait while you finish with my young friend."
