"Well, I've seen Latimer. I wrote to him directly I got back, reminded him who I was, and told him I wanted to have a chat with him about some very special private business. He asked me to come round to his rooms in Jermyn Street last night at ten o'clock, and I was there till pretty near midnight.

"I thought I was bound to find out something, but good Lord, Neil, it came off in a way I'd never dared hope for. Practically speaking, I've got to the bottom of the whole business—at least so far as Latimer's concerned. You see he either had to explain or else tell me to go to the devil, and as he thought I was a perfectly safe sort of chap to be honest with, he decided to make a clean breast of it.

"To start with, it's very much what we suspected. Latimer is a Secret Service man, and that's how he comes to be mixed up in the job. It seems that some little while ago the Admiralty or one of the other Government departments got it into their heads that there were a number of Germans over in England spying out the land in view of a possible row over this Servian business. Latimer was told off amongst others to look into the matter. He had been sniffing around for some weeks without much luck, when more or less by chance he dropped across the track of those two very identical beauties who ran down Gow's boat in the Thames last Friday.

"Somehow or other they must have got wind of the fact that he was after them, and they evidently made up their minds to get rid of him. They seem to have set about it rather neatly. The man with the scar, who is either one of them or else in with them, introduced himself to Latimer as a member of the French Secret Service. He pretended that he had some special information about the case in hand, and although Latimer was a bit suspicious, he agreed to dine at Parelli's and hear what the fellow had to say.

"Well, you know the rest of that little incident. If it hadn't been for you there's not the faintest doubt that Latimer would have copped it all right, and I can tell you he's by way of being rather particularly grateful. I was specially instructed to send you a message to that effect next time I was writing.

"What the connection is between your crowd and these Germans I can't exactly make out. Of course if you're right in your idea about the chap with the scar spying on you in London it's perfectly obvious they're working together in some way. At the same time I'm quite sure that Latimer knows nothing about it. The reason he came down to look at the hut on Friday was because a report about it had been sent to him by one of his men—he has two fellows working under him—and he thought it might have something to do with the Germans. He described the way you had caught him quite frankly, and told me how he'd had to invent a lie about the Surveyor in order to get out of it.

"Exactly what he means to do next I don't know. He has got some plan on, and I've a notion he wants me to help him—at least he sounded me pretty plainly last night as to whether I'd be game to lend him a hand. I need hardly tell you I jumped at the idea. It seems to me our only possible chance of finding out anything. I am to see him or hear from him tomorrow, and directly I know what's in the wind I'll either write to you or come and look you up.

"Joyce will tell you all about George and McMurtrie. If they aren't both up to some kind of particularly dirty mischief I'll eat my whole wardrobe. We must talk it over thoroughly when we meet.

"I'm longing to see you again, and hear all about the work and what's been going on down there.

"So long, old son,
