At this juncture in his thoughts a taxi with flag erect turned the corner of the street ahead.  Tommy held his breath.  Would they hail it?

He drew a sigh of relief as they allowed it to pass unchallenged.  Their course was a zigzag one designed to bring them as quickly as possible to Oxford Street.  When at length they turned into it, proceeding in an easterly direction, Tommy slightly increased his pace.  Little by little he gained upon them.  On the crowded pavement there was little chance of his attracting their notice, and he was anxious if possible to catch a word or two of their conversation.  In this he was completely foiled; they spoke low and the din of the traffic drowned their voices effectually.

Just before the Bond Street Tube station they crossed the road, Tommy, unperceived, faithfully at their heels, and entered the big Lyons’.  There they went up to the first floor, and sat at a small table in the window.  It was late, and the place was thinning out.  Tommy took a seat at the table next to them, sitting directly behind Whittington in case of recognition.  On the other hand, he had a full view of the second man and studied him attentively.  He was fair, with a weak, unpleasant face, and Tommy put him down as being either a Russian or a Pole.  He was probably about fifty years of age, his shoulders cringed a little as he talked, and his eyes, small and crafty, shifted unceasingly.

Having already lunched heartily, Tommy contented himself with ordering a Welsh rarebit and a cup of coffee.  Whittington ordered a substantial lunch for himself and his companion; then, as the waitress withdrew, he moved his chair a little closer to the table and began to talk earnestly in a low voice.  The other man joined in.  Listen as he would, Tommy could only catch a word here and there; but the gist of it seemed to be some directions or orders which the big man was impressing on his companion, and with which the latter seemed from time to time to disagree.  Whittington addressed the other as Boris.

Tommy caught the word “Ireland” several times, also “propaganda,” but of Jane Finn there was no mention.  Suddenly, in a lull in the clatter of the room, he got one phrase entire.  Whittington was speaking.  “Ah, but you don’t know Flossie.  She’s a marvel.  An archbishop would swear she was his own mother.  She gets the voice right every time, and that’s really the principal thing.”

Tommy did not hear Boris’s reply, but in response to it Whittington said something that sounded like:  “Of course—­only in an emergency....”

Then he lost the thread again.  But presently the phrases became distinct again whether because the other two had insensibly raised their voices, or because Tommy’s ears were getting more attuned, he could not tell.  But two words certainly had a most stimulating effect upon the listener.  They were uttered by Boris and they were:  “Mr. Brown.”
