The scene takes place in a dark and gloomy landscape, typical of Munch's expressionist style. In the centre of the painting, a sinister figure is moving towards the viewer. This killer, his face covered by a greenish and amorphous mass, advances with a clearly threatening intention. The lack of defined facial features amplifies the disturbing character of the figure. The background of the painting is a desolate landscape, with twisted trees and a turbulent sky that seems to reflect the emotional turmoil of the scene. The predominant colours are dark and muted, with shades of green, brown and black that create an oppressive atmosphere. Munch's technique is fast and careless, which adds a sense of urgency and chaos to the work. To the left of the killer, the figure of the victim can be seen, fallen on the ground, with an expression of horror frozen on his face. The blood mixes with the earth, creating a disturbing contrast with the dark colours of the surroundings. The lighting is dim, with deep shadows hiding details and heightening the sense of mystery and danger. Munch's inspiration for this work is not clearly documented, but it is thought that he might have been influenced by his own nervous breakdowns and his time in a sanatorium. The painting reflects his obsessions with danger, anxiety and the dark side of human nature.
