How did chekhov's description of the setting support the banker's evil plan to kill the lawyer?

Chekhov's description of the setting creates a tense and oppressive atmosphere that mirrors the banker's dark intentions. The isolation of the lawyer in the locked room heightens the sense of entrapment, emphasizing the banker's cold determination to eliminate him. The oppressive environment serves to amplify the moral decay of the banker, making his nefarious plan feel all the more sinister as it unfolds within this bleak backdrop. Thus, the setting becomes a reflection of the inner turmoil and malevolence driving the banker's actions.
