"Not a sound; no one has followed—that is good," giggled the Belgian, for he was an amiable little fellow. "One has to be careful in these day, messieurs; for there are spies throughout Belgium, and they know well that there are people, like myself, patriots, my friends, who carry on this traffic. But none have seen us, and therefore we are not likely to be disturbed. Now, on, messieurs, and have no fear, for there are no holes and gullies into which you can tumble, while, seeing that it has been dry weather, there is no water in the sewer."
Feeling their way by stretching out their hands, and stumbling along in the darkness, Henri following immediately after the Belgian, then Jules, and last of all Stuart, the party traversed a long stretch of the sewer, their fingers every second or so touching the brick walls on either side, while occasionally their feet splashed through puddles. Then the narrow path they trod swung to the left, and for a moment a breath of cold air blew in upon them, and, glancing overhead, Henri caught just a fleeting glimpse of stars far above, and of the iron bars of a grid stretching between him and the sky.
"Now to the left, messieurs, and we descend. Listen, we are nearly under the Dutch frontier, and overhead stretch those highly-charged electric wires which have been erected by the Germans, and on which many a poor fellow has been electrocuted. But even fear of electrocution cannot keep the brave sons of Belgium from endeavouring to leave this invaded country, and from joining those Belgian troops now fighting with the French and the British. No, I who lead you now have led hundreds of young fellows by this path or a similar one, and have taken them to safety. Now on, messieurs; in a little while we shall ascend to the surface."
It was perhaps a quarter of an hour later that Henri felt that the path under his feet was ascending, and presently, having in the meanwhile been half stifled, he began to appreciate the fact that fresh air was reaching him, and that he could breathe more easily. A warning cry from the man who led them now brought him to a halt, and five minutes later the whole party had clambered up the rungs of a ladder and had gained the Open.
"Messieurs," said the Belgian, "beyond there, straight ahead, you will find a town with friendly Dutchmen in it, who will feed you and clothe you and send you to your people. Adieu! You will fight all the better for these adventures, and all the more fiercely for having seen what poor Belgium is like under the Germans. Adieu! And good luck go with you."
Shaking hands with their deliverer, and thanking him most cordially, Henri and Jules and Stuart saw him depart down the ladder, and then turned their faces from unhappy Belgium into Holland. For, indeed, they were now beyond the frontier, and, looking back, could see the barbed-wire fence which separated Holland and Belgium, erected to keep patriotic sons of the invaded country from escaping German control and joining the Belgian forces under King Albert. Yes, they could see the light shot from a small moon, which had now risen, shining on the wires, shining on that lower one which was charged with an electric current.
"Nasty thing to get up against, that," said Stuart, the big, hefty Stuart, shuddering in spite of himself. "I expect many a poor devil has been killed by that method. And what a method! Just the sort of thing a German would do. Now isn't it a mean, underhand way of killing people? But never mind, here are three of us who mean to get even with them; and in the meanwhile what about getting forward? What about something to eat? What about something to smoke? What about joining people who ain't afraid of smiling, who've pot a friendly feeling for British and French, and don't give a rap for the Germans?"
The warmest of welcomes indeed waited the three in that Dutch town which they were approaching, and despite the late hour of their arrival they were immediately accommodated in one of the houses, were given an opportunity of bathing, and were provided with suitable clothing and with a meal the like of which they had not seen for many a long day.
"And now," said Henri on the following morning, when they assembled in the salon of the house to which they had been invited, "and now, Stuart, what happens? Naturally enough, Jules and I make for France by the quickest route, and then join the army."
"Which looks to me as though you're suggesting that I'm going to do something quite different," growled Stuart, looking impressively big in the Dutch clothes which had been provided for him. "Just as naturally enough as you two are going to join the French army, I am off to join the British—Kitchener's, you know—to take a hand in the job of smashing the Kaiser."
