Suddenly Jones was seen to rise up in the other boat, and Leonard, divining his intention, cried out in a loud voice:
“Look out! Duck!”
In spite of their surprise, all obeyed.
From the first boat there came a puff of smoke, followed by a sharp crack. Something whined over the Sybil.
“They are shooting at us,” said Leonard calmly. “You girls keep down in the boat.”
“Two can play at that game,” said one of the officers.
He drew his own revolver, and brought it to bear. But before he could fire, Shirley sprang to her feet and seized his arm.
“Careful,” she said, “you are likely to hit Jimmy.”
The officer lowered his weapon.
