Part 28

"That door has been locked for ages. The room on the other side is one like this, with a door in the corridor; it is used chiefly to store old documents of no great importance, and I believe that whole stacks of them, in bundles, are piled against the other side of that same door. We will send for the key and see, if you like."

The key was sent for, and the door from the corridor opened. As Telfer had led us to expect, the place was full of old papers in bundles and parcels, thick with ancient dust, and these things were piled high against the door next his room, and plainly had not been disturbed for months, or even years.

"There remains the skylight," said Hewitt, "for I perceive, Mr. Telfer, that your room is lighted from above, and has no window; while the grate is a register. There seems to be no opening in that skylight but the revolving ventilator. Am I right?"

"Quite so. There is no getting in by the skylight without breaking it, and, as you see, it has not been broken. Certainly there are men on the roof repairing the leads, but it is plain enough that nobody has come that way. The thing is wholly inexplicable."

"At present, yes," Hewitt said, musingly. He stood for a few moments in deep thought.

"Plummer is longer away than I expected," he said presently. "By the way, what was the external appearance of the missing code?"

"It was nothing but a sort of thin manuscript book, made of a few sheets of foolscap size, sewn in a cover of thickish grey paper. I left it in the safe doubled lengthwise, and tied with tape in the middle."

"Its loss is a very serious thing, of course?"

"Oh, terribly, terribly serious, Mr. Hewitt," Telfer replied, despairingly. "I am responsible, and it will put an end to my career, of course. But the consequences to the country are more important, and they may be disastrous--enormously so. A great sum would be paid for that code on the Continent, I need hardly say."

"But now that you know it is taken, surely the code can be changed?"

"It's not so easy as it seems, Mr. Hewitt," Telfer answered, shaking his head. "It means time, and I needn't tell you that with affairs in their present state we can't afford one moment of time. Some expedients are being attempted, of course, but you will understand that any new code would have to be arranged with scattered items of the fleet in all parts of the world, and that probably with the present code in the hands of the enemy. Moreover, all our messages already sent will be accessible with very little trouble, and they contain all our strategical coaling and storing dispositions for a great war, Mr. Hewitt; and they can't, they can't be altered at a moment's notice! Oh, it is terrible!... But here is Inspector Plummer. No news, I suppose, Mr. Plummer?"

"Well, no," Plummer answered deliberately. "I can't say I've any news for you, Mr. Telfer, just yet. But I want to talk about a few things to Mr. Hewitt. Hadn't we better go and see if your telegram is answered, Mr. Hewitt? Unless you've heard."

"No, I haven't," Hewitt replied. "We'll go on at once. Good-day for the present, Mr. Telfer. I hope to bring good news when next I see you."

"I hope so, too, Mr. Hewitt, most fervently," Telfer answered; and his looks confirmed his words.

We walked in silence through the corridor, down the stairs, and out by the gates into the street. Then Plummer turned on his heel and faced Hewitt.

"That man's a wrong 'un," he said, abruptly, jerking his thumb in the direction of the office we had just left. "I'll tell you about it in the cab."

As soon as our cab was started on its way back to Hewitt's office Plummer explained himself.

"He's been watched," he said, "has Mr. Telfer, when he didn't know it; and he'll be watched again for the rest of to-day, as I've arranged. What's more, he won't be allowed to leave the office this evening till I have seen him again, or sent a message. No need to frighten him too soon--it mightn't suit us. But he's in it, alone or in company!"

"How do you know?"

"I'll tell you. It seems the lead roofs are being repaired at the Admiralty, and the plumbers are walking about where they like. Now I needn't tell you I've had a man or two fishing about among the doorkeepers and so on at the Admiralty, and one of them found a plumber he knew slightly, working on the roof. That plumber happens to be no fool--a bit smarter than the detective-constable, it seems to me, in fact. Anyhow, he seems to have got more out of my man than my man got out of him; and soon after I reached the Yard he turned up, asking to see me. He said he'd heard that a valuable paper was missing (he didn't know what) from the room with the skylight in the top floor, where the gentleman with the single eye-glass was, and where the safe was let in the wall; and he wanted to know what would be the reward for anybody giving information about it. Of course I couldn't make any promise, and I gave him to understand that he would have to leave the amount of the reward to the authorities, if his information was worth anything; also, that we were getting to work fast, and that if he wished to be first to give information he'd better be quick about it; but I promised to make a special report of his name and what he had to say if it were useful. And it will be, or I'm vastly mistaken! For just you see here. Our friend, Mr. Telfer, says he put that code safely away at 10.20 in the safe, and that he never went to the safe again till 12.20, when the Controller's secretary was with him; never went to it for anything whatever, observe. Well, the plumber happened to be near the skylight at half-past eleven, and he is prepared to swear that he saw Mr. Telfer--'the gent with the eye-glass,' as he calls him--go to the safe, unlock it, take out a grey paper, folded lengthwise, with red tape round it, re-lock the safe, and carry that paper out into the corridor! The plumber was kneeling by a brazier, it seems, which was close by the skylight, and he is so certain of the time because he was regulating his watch by Westminster Hall clock, and compared it when the half-hour struck, which was just while Telfer was absent in the corridor with the paper. He was only gone a second or two, and you will remember that Corder saw Mayes leaving the premises within two minutes of that time!"

"Yes!"

"Well, Telfer was back in a second or two, without the paper, and went on with his affairs as before. That's pretty striking, eh?"

"Yes," Hewitt answered thoughtfully, "it is."

"It was a sort of shot in the dark on the part of the plumber, for he knew nothing else--nothing about Telfer legitimately having the keys of the safe, nor any of the particulars we have been told. He merely knew that a paper was missing, and having seen a paper taken out of the safe he got it into his 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." #/
