The first thing Jimmy did the next morning was to call upon the head of the recently organized Intelligence Bureau of the War Department--not the Intelligence Division which has charge of censorship and the handling of news, but the bureau which bears the same relation to the army that the Secret Service does to the Treasury Department. "From what ports are transports sailing within the next couple of weeks?" he inquired of the officer in charge. "From Boston, New York, Norfolk, and Charleston," was the reply--merely confirming Callahan's previous belief. He had hoped that the ground would be more limited, because he wanted to have the honor of solving this problem by himself, and it was hardly possible for him to cover the entire Atlantic Coast. "Where's the biggest ship sailing from?" was his next question. "There's one that clears Norfolk at daylight on Monday morning with twelve thousand men aboard...." "Norfolk?" interrupted Callahan. "I thought most of the big ones left from New York or Boston." "So they do, generally. But these men are from Virginia and North Carolina. Therefore it's easier to ship them right out of Norfolk--saves time and congestion of the railroads. As it happens, the ship they're going on is one of the largest that will clear for ten days or more. All of the other big ones are on the other side." "Then," cut in Callahan, "if the Germans wanted to make a ten-strike they'd lay for that boat?" "They sure would--and one torpedo well placed would make the _Tuscania_ look like a Sunday-school picnic. But what's the idea? Got a tip that the Huns are going to try to grab her?" "No, not a tip," Callahan called back over his shoulder, for he was already halfway out of the door; "just a hunch--and I'm going to play it for all it's worth!" The next morning, safely ensconced at the Monticello under the name of "Robert P. Oliver, of Williamsport, Pa." Callahan admitted to himself that he was indeed working on nothing more than a "hunch," and not a very well-defined one at that. The only point that appeared actually to back up his theory that the information was coming from Norfolk was the fact that the U-boat was known to be operating between New York and the Virginia capes. New York itself was well guarded and the surrounding country was continually patrolled by operatives of all kinds. It was the logical point to watch, and therefore it would be much more difficult to obtain and transmit information there than it would be in the vicinity of Norfolk, where military and naval operations were not conducted on as large a scale nor with as great an amount of secrecy.
