At first glance one might have been inclined to believe the buildings untenanted. There seemed to be no one stirring about the place, and some of the unshuttered windows on the second floor were broken. The only indications of recent occupation were a pile of kegs at the rear of the house and near-by a heap of freshly opened tin cans. Near one of the larger outbuildings, too, was a pile of chips and sawdust.
"There does not seem to be any one about," whispered Jane. "What do you suppose they do here?"
"I can't imagine yet," said Fleck with an impatient shake of his head.
"The fact that this house is important enough for the Hoffs to visit once a week makes it important for us to cautiously and carefully investigate everything about it. It may be a secret wireless plant away off here in the woods where no one would think of looking for it. It might be a bomb factory where their chemists manufacture the bombs and explosives with which they are constantly trying to wreck our munition plants and communication lines. Perhaps it is just a rendezvous where their various agents, the important ones engaged in their damnable work of destruction, come secretly to get their orders from the Hoffs and to receive payment for their hellishness accomplished."
"It's all so funny, so perfectly absurd," said Jane with a nervous little laugh.
"Absurd," cried Fleck indignantly, "what do you mean? It's frightfully serious."
