From publisher blurb:
Border Crossing is a daring mission across the Iron Curtain when conventional methods have failed to gain vital knowledge. This adventure postulates the operation of a Covert Action Team in“modern” East Germany. Missions like this are the last resort of the intelligence community when remote means fail and there is no agent-in-place, or (in this case), the agent-in-place has been neutralized by enemy action. Time is critical1 there is no time to cultivate a new agent, so the last resort becomes the only hope.
