The quote "What we're in is a vacuum," from Henning Mankell's book "One Step Behind," suggests a state of emptiness or a lack of direction. This could relate to personal feelings of uncertainty or a broader sense of societal stagnation. The imagery of a vacuum implies that something essential is missing, leaving individuals or communities in a state of confusion or disarray.

Mankell's work often explores complex human emotions and societal issues. The use of the term "vacuum" evokes a deeper reflection on the challenges characters face in navigating their lives and the world around them. It can symbolize isolation, an absence of meaningful connections, or the struggle to find purpose amidst chaos.
