'I had learned,' he went on, turning his curious, full, ruminating eyes on me, 'that the British working-man is about the soundest piece of humanity on God's earth. He grumbles a bit and jibs a bit when he thinks the Government are giving him a crooked deal, but he's gotten the patience of job and the sand of a gamecock.
And he's gotten humour too, that tickles me to death. There's not much trouble in that quarter for it's he and his kind that's beating the Hun ... But I picked up a thing or two besides that.'
He leaned forward and tapped me on the knee. 'I reverence the British Intelligence Service. Flies don't settle on it to any considerable extent. It's got a mighty fine mesh, but there's one hole in that mesh, and it's our job to mend it. There's a high-powered brain in the game against us. I struck it a couple of years ago when I was hunting Dumba and Albert, and I thought it was in Noo York, but it wasn't. I struck its working again at home last year and located its head office in Europe. So I tried Switzerland and Holland, but only bits of it were there. The centre of the web where the old spider sits is right here in England, and for six months I've been shadowing that spider. There's a gang to help, a big gang, and a clever gang, and partly an innocent gang. But there's only one brain, and it's to match that that the Robson Brothers settled my duodenum.'
I was listening with a quickened pulse, for now at last I was getting to business.
'What is he - international socialist, or anarchist, or what?'
I asked.
'Pure-blooded Boche agent, but the biggest-sized brand in the catalogue - bigger than Steinmeier or old Bismarck's Staubier.
Thank God I've got him located ... I must put you wise about some things.'
He lay back in his rubbed leather armchair and yarned for twenty minutes. He told me how at the beginning of the war Scotland Yard had had a pretty complete register of enemy spies, and without ****** any fuss had just tidied them away. After that, the covey having been broken up, it was a question of picking off stray birds.
That had taken some doing. There had been all kinds of inflammatory stuff around, Red Masons and international anarchists, and, worst of all, international finance-touts, but they had mostly been ordinary cranks and rogues, the tools of the Boche agents rather than agents themselves. However, by the middle Of 1915 most of the stragglers had been gathered in. But there remained loose ends, and towards the close of last year somebody was very busy combining these ends into a net. Funny cases cropped up of the leakage of vital information.
They began to be bad about October 1916, when the Hun submarines started on a special racket. The enemy suddenly appeared possessed of a knowledge which we thought to be shared only by half a dozen officers. Blenkiron said he was not surprised at the leakage, for there's always a lot of people who hear things they oughtn't to.
What surprised him was that it got so quickly to the enemy.
Then after last February, when the Hun submarines went in for frightfulness on a big scale, the thing grew desperate. Leakages occurred every week, and the business was managed by people who knew their way about, for they avoided all the traps set for them, and when bogus news was released on purpose, they never sent it.
A convoy which had been kept a deadly secret would be attacked at the one place where it was helpless. A carefully prepared defensive plan would be checkmated before it could be tried. Blenkiron said that there was no evidence that a single brain was behind it all, for there was no similarity in the cases, but he had a strong impression all the time that it was the work of one man. We managed to close some of the bolt-holes, but we couldn't put our hands near the big ones.
'By this time,' said he, 'I reckoned I was about ready to change my methods. I had been working by what the highbrows call induction, trying to argue up from the deeds to the doer. Now Itried a new lay, which was to calculate down from the doer to the deeds. They call it deduction. I opined that somewhere in this island was a gentleman whom we will call Mr X, and that, pursuing the line of business he did, he must have certain characteristics. Iconsidered very carefully just what sort of personage he must be. Ihad noticed that his device was apparently the Double Bluff. That is to say, when he had two courses open to him, A and B, he pretended he was going to take B, and so got us guessing that he would try A.
Then he took B after all. So I reckoned that his camouflage must correspond to this little idiosyncrasy. Being a Boche agent, he wouldn't pretend to be a hearty patriot, an honest old blood-and-bones Tory. That would be only the Single Bluff. I considered that he would be a pacifist, cunning enough just to keep inside the law, but with the eyes of the police on him. He would write books which would not be allowed to be exported. He would get himself disliked in the popular papers, but all the mugwumps would admire his moral courage. I drew a mighty fine picture to myself of just the man I expected to find. Then I started out to look for him.'
Blenkiron's face took on the air of a disappointed child. 'It was no good. I kept barking up the wrong tree and wore myself out playing the sleuth on white-souled innocents.'
'But you've found him all right,' I cried, a sudden suspicion leaping into my brain.
'He's found,' he said sadly, 'but the credit does not belong to John S. Blenkiron. That child merely muddied the pond. The big fish was left for a young lady to hook.'
'I know,' I cried excitedly. 'Her name is Miss Mary Lamington.'
He shook a disapproving head. 'You've guessed right, my son, but you've forgotten your manners. This is a rough business and we won't bring in the name of a gently reared and pure-minded young girl. If we speak to her at all we call her by a pet name out of the _Pilgrim's _Progress ... Anyhow she hooked the fish, though he isn't landed. D'you see any light?'
'Ivery,' I gasped.
