The party had walked possibly five miles, when, from behind, they heard
the sudden booming of a great gun.

"Faster," said Hal, and broke into a trot. The others followed suit.

"Suppose they have discovered our flight, or the gun was some other
signal?" said Chester.

"I don't know," said Hal. "It's as likely to be one as the other. The
farther away we get the better."

More guns now shattered the stillness of the night, growing closer
and closer.

"They are after us, all right," declared Hal.

Without pausing, he glanced quickly around. Then suddenly he swerved
sharply to the left.

"Why this change in course?" panted Chester.

"See that woods?" demanded Hal, pointing.

"Yes."

"Well, we may find safety there. It's a long chance."

They dashed into the shelter of the little woods a moment later.

Hal stopped and turned to Helen.
