Yet all my efforts were, alas! in vain.

They had evidently changed their route to London a second time, and had travelled from Bâle to Brussels and Ostend!

The thought occurred to me as I stood watching the last passengers leaving the steamer. If they had travelled direct by way of Ostend, then they would be seated in the train for Charing Cross, for the Ostend boat had been in half an hour, we were told.

The train, one of those gloomy, grimy, South-Eastern "expresses," was waiting close by. Therefore I ran frantically from end to end, peering into each carriage, but, to my dismay, the men I sought were not there!

So Fournier and I entered a first-class compartment and, full of bitter disappointment, travelled up to Charing Cross, where we arrived about seven o'clock.

I was alighting from the train into the usual crowd of arriving passengers, and their friends who were present to meet them, for there is always a quick bustle when the boat-train comes alongside the customs barrier, when of a sudden my quick eyes caught sight of two men in Homburg hats and overcoats.

My heart gave a bound.

Vernon and Jeanjean had alighted from the same train in which I and Fournier had travelled, and were hurrying out of the station.

Jeanjean carried a small brown leather handbag, while Vernon had only a walking-stick. Both men looked fagged, weary and travel-worn.

"Look!" I whispered to Fournier. "There they are!"
