As the story continues, Blake’s character is gradually revealed. Describe his personality, using evidence from the story

Mr. Blake is a business man who holds an important enough executive position to warrant having a private secretary. He is petty and snobbish and almost certainly suffering some manner of a personality disorder dependent on an elevated level of narcissism for diagnosis. He punishes both wife and son for what he views as their betrayal of his authority and he wields that authority like a club at the workplace. His alienation and isolation from genuine emotional contact with other people has endowed him with a false impression of his own intelligence and cleverness which ultimately leads to his downfall at the hands of Miss Dent, a woman he views as lacking such necessary attributes to cause him lasting harm.
