"What is it—oh, what is it?" palpitated Elsie.
Frank turned to Hodge.
"Did you see that man?" he hoarsely asked.
Bart was startled and astounded by the terrible look on Merriwell's face and the glare in his usually kindly eyes.
"What man?"
"The one in black—the old man who nearly knocked Inza into the river over on the Canadian side."
"Was it him? I saw some one running, among the trees yonder. What happened, Merry? How did——"
"Look out for the girls—guard them," commanded Frank.
Then he sprang away with the speed of a deer, quickly disappearing from view in pursuit of the mysterious man, for he now knew that twice that day had that man made an attempt on the life of Inza Burrage.
In the meantime, Elsie was kneeling on the ground, her arms about Inza, trying to learn what had taken place.
