"No further than you can see, my dear Molly," laughed the crafty man. "We were both of us trained in the same excellent school--that school which is the eyes and ears of the great and invincible Imperial Army of the Fatherland. Where would be that army, with our Kaiser at its head, if it had no eyes and no ears? Every report we send to Berlin is noted; every report, however small and vague, is one step towards our great goal and final victory. The Allies may beat themselves against our steel and concrete ring, but they will never win. We sit tight. Our men sit in their comfortable dug-outs to wait--and to wait on until the Allies beat themselves out in sheer exhaustion. Our great invincible nation must win in this island, for one reason--because the German eagle has already gripped in her talons the very official heart of Great Britain herself. Our Kaiser Wilhelm is only William of Normandy over again. In Berlin we hold no apprehensions. We know we must win. If not to-day--well, we sit safe in our trenches in Flanders, or give the gallant Russians a run just to exercise them--knowing well that victory must be ours when we will it!"

I managed to find that envelope in his desk on the day before he was discharged. It came in extremely useful, as I expected it might." "So the charge against him cannot fail?" asked the handsome woman, puffing slowly at her cigarette. "Remember, he may suspect you--knowing all that he does!" "Bah! The charge cannot fail. Of course I've had nothing to do with the matter as far as the authorities are concerned. I have simply slipped the noose over his head, and shall let the Intelligence Department do the rest. They will do their work well--never fear." "But you told the Intelligence Department about that Dr Jerrold?"
