He promised, however, to tell the whole story to the consul when he returned, and pointed out that in due course, no doubt, the Foreign Office would be informed. In the meantime, Jimmy was to keep his eyes open and his mouth shut. On no account whatsoever was he to say a word to any one of what he knew.

The boy was determined to remember this advice, which--strangely enough--coincided with that of Rudolf Stork. As he came down the front doorsteps of the consulate, though he was out of work and practically a pauper, though he was conscious of the fact that he was living on the charity of others who could not afford to support him and upon whom he had no claim, he walked with a lighter tread than ever in his life before. He could not but feel proud of the fact that, for some mysterious reason, he was, indeed, a person of importance.

A man was leaning against the railings, both hands thrust deep in his trousers pockets, a battered hat jammed over his eyes--one of the inevitable loafers who are to be found in the streets of every city in the world. As Jimmy reached the bottom step, this man looked at him sharply from over his shoulder, and then slouched away.

The boy stood stock still, staring after the man with the battered hat, with parted lips and widely opened eyes. He did not speak or move, until Peggy suddenly touched his arm.

"Did you see that man?" he whispered.

"What is it?" Peggy exclaimed. "What's the matter, Jimmy?"

Jimmy pointed to the receding figure which just then disappeared quite suddenly round a corner.

"That man," said he, "was Rudolf Stork. And he knows I saw him."

If we put away ghosts and such like--in which nobody nowadays believes--there is, perhaps, no more unpleasant experience in the world than to be shadowed. The fact that one's footsteps are dogged eternally, that at every sudden corner or darkened by-way a hidden foe may lurk, is the kind of thing that is well calculated to test the strongest nerves.
