"Yes. Ever heard of a woman called The Yellow Typhoon?"

"No," said Mathison, after a moment.

"Well, perhaps a man like you wouldn't. But ask the gay lads from Yokohama to Shanghai, and they'll tell you Typhoon is a happy choice.... God's name, look at this room! What a fight!... And I stood yawping while she ran away again! Well, she sha'n't get outside the Bay. You may lay to that. Now then, anything missing?"

"A blue-print, relative to the U-boat business."

"But I thought that completed and out of the way!"

"It is; but Bob had some ends to tighten up.... My God, Morgan, they struck him from behind! He was beating them off, and they struck him from behind!"

"Buck up, Mathison! You mustn't let this get you. There's a whale of a man's job in front of you. Uncle Sam's depending on you to get to Washington. Don't let this get to your nerves.... Old Bob Hallowell! I'll round up the suspects. I'll crucify them, but some one will speak. How valuable was the print?"

"It will give them an idea of what they'll be up against, and that will rob the thing of fifty per cent. of its value. The surprise will be gone."

"I see. Bad business. They'll try to get East; Mexican wireless. Well, it will take a clever man or woman to slip through my net; and I'll settle it inside an hour. I suppose they came by the river. We'll take a look-see there later. Remember this is ordinary burglary with murder. It won't do to let the public know that anything serious has happened to our war plans."

"My friend!... And he was so happy to have done something for his country!"
