"And who will be aware of the matter?"
"Only myself," was Weirmarsh's reply. "And I think that you may trust a secret with me?"
The old man made no reply, and the crafty doctor wondered whether by silence he very reluctantly gave his consent.
CHAPTER VIII
PAUL LE PONTOIS
There is in the far north-west of France a broad, white highway which runs from Châlons, crosses the green Meuse valley, mounts the steep, high, tree-fringed lands of the Côtes Lorraines, and goes almost straight as an arrow across what was, before the war, the German frontier at Mars-la-Tour into quaint old Metz, that town with ancient streets, musical chimes, and sad monument to Frenchmen who fell in the disastrous never-to-be-forgotten war of '70.
This road has ever been one of the most strongly guarded highways in the world, for, between the Moselle, at Metz, and the Meuse, the country is a flat plain smiling under cultivation, with vines and cornfields everywhere, and comfortable little homesteads of the peasantry. This was once the great battlefield whereon Gravelotte was fought long ago, and where the Prussians swept back the French like chaff before the wind, and where France, later on, defeated the Crown Prince's army. The peasants, in ploughing, daily turn up a rusty bayonet, a rotting gun-stock, a skull, a thigh-bone, or some other hideous relic of those black days; while the old men in their blouses sit of nights smoking and telling thrilling stories of the ferocity of that helmeted enemy from yonder across the winding Moselle. In recent days it has been again devastated by the great world war, as its gaunt ruins mutely tell.
That road, with its long line of poplars, after crossing the ante-war French border, runs straight for twenty kilomètres towards the abrupt range of high hills which form the natural frontier of France, and then, at Haudiomont, enters a narrow pass, over twelve kilomètres long, before it reaches the broad valley of the Meuse. This pass was, before 1914, one of the four principal gateways into France from Germany. The others are all within a short distance, fifteen kilomètres or so—at Commercy, which is an important sous-prefecture, at Apremont, and at Eix. All have ever been strongly guarded, but that at Haudiomont was most impregnable of them all.
