Ferralti understood, and dashed forward again at full speed. Tommaso also understood, for his face was white and he muttered terrible oaths as he pressed on. Yet run as they might, the mad duchessa was inspired with a strength so superhuman that she kept well in advance.
But the narrow path ended half way up the cliff. It ended at a deep chasm in the rocks, the edge of which was protected by a large flat stone, like the curb of a well.
With a final leap the old woman gained this stone, and while the dreadful pit yawned at her feet she turned, and with a demoniacal laugh faced her pursuers, hugging the child close to her breast.
Tommaso and Ferralti, who were nearest, paused instinctively. It was now impossible for them to prevent the tragedy about to be enacted. The Duke, spurred on by fear, was yet twenty paces in their rear, and in a moment he also stopped, clasping his hands in a gesture of vain entreaty.
"Listen, Lugui!" his mother called to him, in a dear, high voice. "This is the child that has come between us and turned you from a man into a coward. Here alone is the cause of our troubles. Behold! I will remove it forever from our path."
With the words she lifted Tato high above her head and turned toward the pit—that terrible cleft in the rocks which was believed to have no bottom.
At her first movement Tommaso had raised his gun, and the Duke, perceiving this, called to him in an agonized voice to fire. But either the brigand wavered between his loyalty to the Duke or the Duchessa, or he feared to injure Tato, for he hesitated to obey and the moments were precious.
The child's fate hung in the balance when Ferralti snatched the weapon from the brigand's hands and fired it so hastily that he scarcely seemed to take aim.
A wild cry echoed the shot. The woman collapsed and fell, dropping Tato at her feet, where they both tottered at the edge of the pit. The child, however, clung desperately to the outer edge of the flat stone, while the Duchessa's inert form seemed to hesitate for an instant and then disappeared from view.
Tommaso ran forward and caught up the child, returning slowly along the path to place it in the father's arms. Ferralti was looking vaguely from the weapon he held to the pit, and then back again, as if not fully understanding what he had done.
