This is Karel, Nadia’s supposed contact man with a high velocity rifle. In fact he is Post 5, positioned 30 miles from The Village on the Polish coast. Number 2 instructed the Supervisor-Number 26 to contact Post 5 just in case. What just in case Post 5 is asleep, busy cooking a meal in the cave, or at the latrine!
Basically Post five is located some distance along the coast from The Village presumably in order to stop potential escapees, hence the high velocity rifle. He is also suggestive, that other such posts are positioned not only up and down the coast, but presumably on both sides of the estuary.
Be seeing you
