Josef walked out into the cold night towards the munitions building. He encountered Franz, the guard, a casual associate of lower rank who he had played cards with a few times. "I've misplaced by pistol and need another one", he told Franz, trying to act as casual as possible. Franz waved him in, saying "help yourself". Josef was starting to think of himself as more of his own agent, and the thought passed quickly that if he put a bullet in Franz, he could take whatever he wanted, grenades, rifles, anything, and be long gone before anyone noticed. But he couldn't bring himself to do it to a unsuspecting fellow German.
Once inside, though, Josef realized that he could probably conceal a rifle under his long winter coat without being detected. After all, Franz would not be suspicious. He quickly tucked one under his coat and went back out carrying the Luger in his gloved hands, and the rifle under his coat. Franz said nothing. As Josef approached his building, he realized this was the moment of truth. Would she be there. He opened the door. "Hello", he said, propping it open.
