"I have made good progress, Diana," he said, "for I have learnt enough
about the enemy to make sure of getting some of them at least into our

"Are you sure?"

"Yes."

"What do you propose to do, then? Tell me."

"Harkaway has a son--a mere youth."

"I know it."

"Well, this boy is a dare-devil, bold and fearless lad; nothing can
daunt him. He is, in fact, what his hated father was when first I knew
him, years and years ago."

A faint and half-suppressed sigh escaped him as he uttered this.

"What of this boy?"

"This boy has a companion called Harry Girdwood."

"Well."

"Well, these two boys are to be trapped, if it be gone about carefully
--very carefully, mark you."
