In "The Business" by Martina Cole, the narrative explores the complexities of relationships and morality within the backdrop of the criminal underworld. The protagonist is deeply influenced by the company they keep, which shapes their identity and decisions. The characters navigate loyalty, betrayal, and ambition, highlighting how associations can define one's path and character.

This theme is encapsulated in the quote, "Show me the company you keep and I'll tell you what you are." It underscores the idea that one's social circle reflects one's values and beliefs, ultimately determining their fate in life and business. The interplay of relationships and the consequences of choices are central to the unfolding drama.
