"It's only a bit of a breeze overhead," said Hone. "We won't stop to listen anyway."

He caught her hand in his once more, grasping it firmly, and they moved forward again. They could see the moonlight glimmering on the water ahead, and in another yard or two the low-growing bush to which Hone had moored the boat became visible.

In that instant, with a jerk of terror, Nina stopped short. "Pat! What is that?"

Hone stood still. "There! Don't be scared!" he said soothingly. "What would it be at all? There's nothing but shadow."

"But there is!" she gasped. "There is! There! On the bank above the boat! What is it, Pat? What is it?"

Hone's eyes followed her quivering finger, discerning what appeared to be a blot of shadow close to the bush above the water.

"Sure, it's only shadow—" he began.

But she broke in feverishly. "It's not, Pat! It's not! There's nothing to cast it. It's in the full moonlight."

"You stay here!" said Hone. "I'll go and have a look."

"I won't!" she rejoined in a fierce whisper, holding him fast. "You—you shan't go a step nearer. We must get away somehow—somehow!" with a hunted glance around. "Not through the undergrowth, that's certain. We—we shall have to go back."
