"And now you are having Telfer supervised?" "I am. Not that we're likely to get the code from him; that's passed out, sure enough, in Mayes's hands--or else his pockets." To this confident expression of opinion Hewitt offered no reply, and presently we alighted at his office, eager to learn if Peytral had given the information Hewitt so much desired. Sure enough a telegram was there, and it ran thus: /# "On the night you know of, Mayes went first to 37 Raven Street, Blackfriars, then to 8 Norbury Row, Barbican. Message follows." #/ "Now we're at work," Hewitt said, briskly, "and for a while we part. I shall make a few changes of dress, and go to take a look at 37 Raven Street, Blackfriars. Will you two go on to Norbury Row? You'll have to be careful, Plummer, and not show yourself. That is where Brett will be useful, since he isn't known; if anybody is to be seen let it be him. I shall be very careful myself--though I shall have some little disguise; and I fancy I shall not be so likely to be seen as you." "What are we to do?" I asked. "Well, of course, if you see Mayes in the open, grab him instantly. I needn't tell Plummer _that_. I think Plummer would naturally seize him on the spot, rush him off to the nearest station and go back with enough men to clear out No. 8 Norbury Row. If you don't see him you'll keep an observation, according to Plummer's discretion. But, unless some exceptional chance occurs, I hope you won't go rushing in till we communicate with each other--we must work together, and I may have news. My instinct seems to tell me that yours is the right end of the stick, at Barbican. But we must neglect nothing, and that is why I want you to hold on there while I make the necessary examination at the other end. Do you know this Norbury Row, Plummer?" "I think I know every street and alley in the City," Plummer answered. "There is a very good publican at the corner of Norbury Row, who's been useful to the police a score of times. He keeps his eyes open, and I shall be surprised if he can't give us _some_ information about No. 8, anyhow. Moon's his name, and the house is 'The Compasses.' I shall go there first. And if you've any message to send, send it through him. I'll tell him." On the stairs Plummer and I encountered another of his assistants. "I've got the cab, sir," he reported. "Waiting outside now. Took up a fare in Whitehall, opposite the Admiralty, and drove him to Charterhouse Street; got down just by the Meat Market. That's all the man seems to know." Plummer questioned the cabman, and found that as a matter of fact that was all he did know. So, telling him to wait to take us our little journey, we returned and reported his information to Hewitt. "Just as I expected," he said, quietly. "He stopped the cab a bit short of his destination, of course,--just as you will, no doubt. There's not a great deal in the evidence, but it confirms my idea."
