that something was hanging over their heads oppressed the two boys. The
country was at war and plotters and spies were abroad in the land. The
events of the last two days had convinced them that High Ridge had its
share of mischief makers, and they felt sure that that very night a blow
would be struck.

A walk of twenty minutes brought them to the factory. The low, brick
buildings loomed ghostly in the darkness, with only here and there an
electric light burning inside as protection against thieves. The small
brick office was situated in front of the other buildings and here a
light was shining brightly.

A guard challenged them. Bob recognized the man as one of his father's
employees, and soon convinced him that he and Hugh were all right. They
passed on and a moment later were in Mr. Cook's office. Mr. Cook was
seated at his desk and in a chair opposite him Sergeant Riley was
ensconced.

"Well," exclaimed the sergeant as the boys entered, "if ever I saw two
hard looking bums you two are it. 'Tis a wonder one of my men didn't
run yez in."

"We were sort of afraid of that," laughed Bob. "No one bothered us
though."

"Where's Heinrich?" inquired Hugh.

"In the next room," said Mr. Cook. "Where's Lena?"

"We lost her."
