Can a psycho detective function as a police officer?

In Neil Mach's crime thriller "Curiosity Killed the Chicken," the author examines whether a psychopath could be a successful police detective.

The main character in his crime novel has a complete disregard for others’ emotions and exhibits a psychopathic personality disorder.

The detective is fearless, bold, and she's unable to restrain her violent impulses.

Moreover, she demonstrates a tendency to disobey authority, she lacks planning skills, and she exhibits exploitative inclinations.

Is this detective suited to her role?

Won't her impulsive behaviour, her harsh attitude, and her lack of self-discipline lead to her making huge blunders and getting herself fired?

In the novel, the author raises several important questions:

• Can individuals diagnosed with aggressive personality disorder become effective police officers?

• Can someone who is fiercely competitive and lacks empathy ever be a successful investigator?

• Can someone who lacks respect for personal boundaries and has no compassion for the vulnerable be a suitable law enforcement officer?

• Won't a psycho detective like A/DS Jan Brading exploit others for their own pleasure?

• Would a psycho detective's unwavering dedication to 'winning' enhance their effectiveness as an investigator or would the tendency bring unnecessary risks?

• Once a psycho detective is determined to carry out a mission, would they be be able to control their behaviour or would they become more reckless?

• Is it feasible for a psycho detective to harness their aggression for practical purposes?

• Won't a psycho detective always be inclined to adopt a competitive mindset— “winning at all costs” on every occasion? How will such a mindset impact an investigation?

In this modern-day crime thriller set in an English County, the psycho detective's mission is to investigate a case of child abduction.

However, the clues left by witnesses are misleading.

Additionally, the the psycho detective's investigation is hindered by institutional failures, flawed leadership, and dysfunctional colleagues.

Will her newly assigned partner help mellow this psycho detective's confrontational tendencies?

Is there any likelihood the psycho detective and her softer partner will discover the whereabouts of the abducted child before it's too late? Will the psycho detective bring an offender to justice?

Or will the managers strip the psycho detective of her rank before she gets to solve the crime?
