What more, indeed, was necessary to complete the picture? Death. Nothing was easier. No conclusion more mathematically certain. With his knife between his teeth the assassin hastily adjusted the straps under her arms. It was but the work of half a minute from the time he had stopped, though to the terror-stricken child it seemed an age of torment. The rags were packed tightly down in the bottom of the basket. "It'll do for a sinker," said the man. Then he cut the thongs that held her arms, severed the ligament that bound her feet, and with one hand removed the cloth from her mouth, while with the other he suddenly pushed his victim over the edge of the stone quai. "Voilà!" Short as was the opportunity, Fouchette gave one terrified shriek as she went over the brink,--a shriek that pierced the river mists and reverberated from the stone walls and parapets and went ringing up and down the surface of the swiftly swirling stream. Again, as she reappeared, battling with the murky waters with desperate stroke and splash, her childish voice rose,-- "Tartar! Tartar!" And yet again, choking with the flood,-- "Tar--Tar--tar!" It was the last thought,--the last appeal,--this despairing cry for the only one on earth she loved,--the only being on earth who loved her. CHAPTER II The piercing cry of Fouchette seemed yet to linger in the misty morning air, thrilling the distant ear, vibrating upon the unstrung nerves of the outcasts beneath the far-away bridges, borne upon the surface of the waters, when it was answered out of the darkness by a sharp, shrill note of sympathy. Those who have heard the wild hyena in his native fastnesses responding to the appeal of its imperilled young might have understood this half-human, half-savage cry of the roused animal. And almost simultaneously came the swift rush of feet that seemed to claw the granite into flying electric sparks. The repulsive face of the convict murderer turned pale at the sound, and at the sight of the glowing eye-balls his ugly teeth clattered against each other. Nevertheless, the instinct of self-preservation made him crouch low, deadly knife in hand, to receive the expected attack. At the sight of le Cochon the dog emitted a howl of wrath. With the marvellous judgment, however, of the trained animal that will not be turned from the trail of a deer by the scent of skunk, this sight scarcely checked his plunge. Tartar's divination was unerring. He wasted no effort in battling with the current or paddling around in a circle, but turned at once and swam rapidly with the stream. He spent no breath in useless vociferation. All his canine strength was put forth to an end. And these instincts were quickly rewarded by the sight of a strange object floating ahead of him,--something a little higher, than the water.
