The conversation continued for some time.  Rabig handed over some papers which the German officer carefully looked over, using a pencil to follow some lines that seemed to be the tracing of a map or plan. Then he folded them up and put them carefully in his pocket, and after a few more sentences had been exchanged Tom heard the clink of money and saw Rabig tuck something away in his belt.  Then the officer stood up and with a curt nod went away toward the bottom of the hill.
