"Of course; you wouldn't be employed here if you were a stupid pig. Well now, Herr Lieutenant Breul ought to be warned."
"That's true. The Herr Lieutenant is not here now; he has gone for the night with the other officers. But it would be better to arrest the man at once. A spy! We'll do for him, me and my mates."
"Not so fast. We must make sure of the man. I ought to hold him under observation. But it is important to keep the matter quiet. The question is, can you manage to let me have a sight of the man without attracting attention?"
The man scratched his head.
"You don't want to enter by the gate, Herr Policeman?"
"No. It would never do to let it get about that a spy was found here."
"Well, it's not an easy matter, but I'll go to the sheds and see what can be done."
The man went away, Kenneth hastened to the spot where he had left his companion.
"Things look possible," he said. "But your uniform is a difficulty. A German officer mustn't enter the enclosure like a thief, and without the password you can't go in by the gate."
"I must simply bluff it out. I'm a friend of Lieutenant Breul. I've played many parts in my time--not without success."
