The other man stopped and threw out his arms, as if he meant to protest that he could do nothing more.
"Father Lucien!" said Thirlwell.

"Black Steve's risking a capsize." They sped past the man upon the bank and Agatha watched the crouching figure in the canoe.

The craft was a short distance in front of, but outside, theirs, and she could see the danger of her being smashed or swamped.

It was plain that the only safe way down was through the slack along the bank, but the man made no effort to reach this smoother belt.
He let the paddle trail in the water while the canoe rocked among the angry waves.

His rashness fascinated Agatha and she could not look away, although she knew she might see him drown.
"Can't you do something ?" she asked Thirlwell.
"No," he said sternly.
