He chose the street passing by the left-hand face of the town-house, and stole along on tiptoe. A narrow beam of light fell obliquely across the street from an upper window on his left, throwing a luminous circle on the townhouse wall just above the level of his head. He skirted the wall, and had reached the mid-point of that face of the square, when a voice suddenly arrested his steps.
"Señor, charity for a poor prisoner. A copper, Señor, for the love of God!"
The voice appeared to come from just above his head. There was something in the tone that seemed familiar, and with a quickening pulse he resolved to test the surmise which had flashed upon him. Retracing his steps for a couple of yards, he looked up, and there, full in the shaft of light from the house opposite, he saw the barred grating of a dungeon, and, pressed against the bars—yes, it was the small elfin face of the gipsy boy Pepito.

"Hist! I may help you," began Jack, but at this moment he heard the clamp-clamp of ammunition boots approaching from round the corner behind him. "The sentry!" he thought. "Silence! I will come back," he whispered.
He crept along the wall on tiptoe, in the direction away from the approaching footsteps. At the same time he heard from within the cell Pepito's shrill voice in song:
