His heart failed him; for, however well the plans had been laid, the blow might miss its aim, or might not cause death.
They were within about one hundred feet of the well.
The young gentleman, wholly ignorant of the danger which threatened him, was thinking of his unhappy friend, Simon Turchi, overpowered by a heart sorrow, tossing on a bed of suffering, while he was on his way to serenade his beloved Mary.

He also, in his own mind, deplored the involved condition of Simon's business affairs, and determined to save him, even at the cost of great personal sacrifices, as soon as his marriage would render him independent.
What would the young cavalier have thought had he known that at a few steps, distance from him, three assassins, hired by Simon Turchi, were lying in wait to kill him.

But no, his mind was filled with compassion and affectionate feelings for his cruel enemy.
The little band was not far from Hoboken Street; Julio gazed fixedly into the darkness to discover if any one was near the well.
Suddenly he perceived a dark shadow advancing.

Trembling in an agony of fear, and in order to make himself known to the ruffians, Julio suddenly drew his sword and exclaimed: "_Al assassino! Ajusto! ajusto!_ Murder! help! help!" But he had spoken too soon for the success of his designs; for, being put upon his guard by this exclamation, Geronimo drew his sword, and placed his back against the wall of the house that he might not be assailed from behind.
The lute-players, screaming from fright, ran away, and Julio stood in the middle of the street brandishing his sword.
All this had passed almost instantaneously after the first alarm given by Julio.

The man whom he had seen coming from the well, followed by two companions, rushed to the side of the street where Geronimo had made a stand to defend himself.
