A dark evening a crime writer Peter Sander drives through a forest when his car runs out of petrol A little distance from the road there is a house with lighted windows and he goes there to borrow a phone Suddenly he trips over a tree root and sprain one foot He lags up the forest road Then there is a shot a moment after running steps A beam cuts through the dark It goes out The steps moves away Peter gets up and stomps up to the house No one responds to his knokking
