"We shall have to try," replied Jack. "A rogue like him can't be allowed to prowl about England free." This was, of course, perfectly true.

"Why did the chap steal the portrait, only to chuck it away again?" I said presently, as we drove along. "Simply to annoy us, or prevent us finding the treasure, even though he daren't go and dig for it at Streatham himself?"

"That's the idea, I should think," said Jack; "that if he can't have it, you shan't!"

Upon reaching the station we found that Mr. Strong was, at anyrate, not to be caught in Kiel. The Bremen train had left just an hour ago, with him in it. There would be another in fifty minutes.

"Gad, Peter, we are in the race, at anyrate, after all!" said Jack, with a guffaw; "if we have any luck in the trains we may catch him yet."

"Let's find out how long he'll have to wait at Hamburg for the Bremen train," I suggested.

We did so, and found to our annoyance that our train reached Hamburg just ten minutes after Strong's was timed to leave that station for Bremen. There would be another one, however, in an hour or less, and a quicker one than his; so that we might get him at Bremen, It would depend upon what should be his next destination.

"It doesn't much matter," I reflected. "If we don't catch him at Bremen we'd better just see where he's gone to and then set off for Streatham, viâ Hanover and Flushing, as quickly as possible. Are you very keen to see him, Jack?"

"It depends," said Jack. "I should dearly like to see him, just once more, in a dark lane and without witness or revolvers, but with a pair of football boots upon my feet. That would be very sweet indeed. At a crowded station, one might get in a little comforting language; but kicking would be out of the question, and therefore the case would not really be met. However, it would be nice just to see his face, when he sees ours, and to tell him one or two things about himself."

So we took train for Bremen viâ Hamburg, and at this latter place we found, to our amusement, that our train, though starting after Strong's, who had already gone on, ran into Bremen a short while before the other; ours being an express.
