head that he had possibly witnessed the theft; and he kept his knowledge to himself till he could see somebody in authority. Mighty keen, too, about a reward!"
"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."
