“Amos,” he finally said, in the other’s ear, “I reckon we’re as one about that. We can’t stand by and see the cause of the Allies suffer through the work of any renegade Belgian, no matter if he is an old man.”

“Good for you, Jack! I like to hear you say that. Now tell me the next step we must take, for talking without deeds isn’t worth a snap.”

“We must go down there, Amos!”

“Now by that I guess you mean we’ll see that he isn’t carrying any information in the shape of a map or news about the Allies’ reserves?” Amos ventured to say.
