Sometimes the setting does the heavy lifting. In a dystopian or deeply corrupt society, any investigator trying to function is forced into moral compromise just by participating. Their ambiguity is a symptom of the world, not necessarily a character flaw. That's what makes books like 'The Power of the Dog' or 'Gorky Park' so powerful—the system itself is the antagonist.

Wait, I need to jump in with Cormoran Strike from Robert Galbraith's series. He's a war veteran with a prosthetic leg, a chaotic personal life, and a deep-seated anger. He frequently withholds information from the police, uses his celebrity client's resources questionably, and his pursuit of truth is often fueled by personal vendetta as much as justice. He's a good man, but a difficult and sometimes ethically flexible one. His partnership with Robin is partly about grounding him.

Does 'The Dresden Files' count? Harry Dresden is a wizard private investigator. He's got a strong 'chivalry' code, but he's also constantly making deals with dangerous entities, breaking the rules of the magical White Council, and his power inherently corrupts. His investigations often force him to choose between bad and worse options, and he accumulates a terrifying amount of personal debt—literal and figurative—along the way. He's always one step away from becoming the monster he fights.

The graphic novel series 'Criminal' by Ed Brubaker and Sean Phillips. Every protagonist is a career criminal, and the 'investigations' are usually heists gone wrong or attempts to solve a betrayal within the underworld. These aren't good guys with a code; they're thieves, killers, and grifters. The moral ambiguity is the entire point—you're following people who live outside society's rules, and their conflicts are about loyalty, survival, and greed, not justice. It's noir at its most pure and uncompromising.

What about 'The Alienist' by Caleb Carr? Dr. Laszlo Kreizler is a criminal psychologist (an 'alienist') in 1896 New York, investigating a serial killer targeting boy prostitutes. His ambiguity comes from his then-radical theories about childhood trauma shaping criminals. He treats the murderer as a subject to be understood, not just a monster to be caught, which puts him at odds with a society that wants simple retribution. His empathy for the killer's origins creates a profound moral tension with his goal of stopping the horrific crimes.

Looking for something more modern and tech-oriented? 'The Girl with the Dragon Tattoo' gives us Lisbeth Salander. While not a detective by trade, she functions as the ultimate investigator—a brilliant, traumatized hacker with a fierce moral code that exists entirely outside the law. She exacts brutal vengeance on those who harm women, she steals information as a matter of course, and she trusts almost no one. Her grayness is absolute; she is both victim and vigilante. Her partnership with journalist Mikael Blomkvist is compelling because he represents a more conventional, though still flawed, morality. Lisbeth operates in the shadows, using methods that are clearly illegal, but often in the service of exposing corruption that the legal system protects. You're forced to question whether her brand of ruthless, extra-judicial justice is not only effective, but necessary. She's a protagonist you root for fiercely, while being acutely aware that you wouldn't want to meet her in a dark alley if she decided you were on her list.

The protagonist in 'The Devil and the Dark Water' by Stuart Turton is a detective in all but name—a detective with a imprisoned criminal mind, to be precise. His methods are ingenious but wholly unscrupulous, and the 'investigation' happens on a doomed ship where the line between sin and salvation is constantly questioned. It’s a masterpiece of atmospheric tension.

What about detectives in fantasy settings? 'The City & The City' by China Miéville is a philosophical detective novel where the ambiguity is baked into the setting. Inspector Tyador Borlú investigates a murder that spans two cities that occupy the same physical space but are separate political and cultural entities. Citizens must 'unsee' the other city. Borlú's moral struggle involves upholding this bizarre, oppressive social construct—'Breach'—or questioning its very foundation. His detective work forces him to navigate and ultimately challenge the deepest taboos of his society, making his journey one of unraveling not just a crime, but the moral fabric of his world.

Oh! What about a detective whose moral ambiguity is religious or spiritual? Someone who believes they are an instrument of a higher power, and that belief justifies any action? That could be terrifying and brilliant. Their internal certainty clashes with the world's morality, creating a fanatic detective. I'm surprised we don't see more of that.

There's a whole subgenre of 'detectives' who are lawyers. 'Presumed Innocent' by Scott Turow is the classic. Rusty Sabich, the prosecutor who becomes the suspect, is the ultimate ambiguous figure. Is he a grieving colleague, a wronged man, or a clever murderer? The entire novel lives in his morally compromised headspace. Even the act of seeking truth is suspect because he's so intimately involved. It makes you question every thought, every memory. The detective work is internal, and the moral crime might be in the thoughts themselves.

I keep coming back to the idea of the detective as a virus. They enter a stable (if corrupt) system, investigate, expose the truth, and then leave chaos in their wake. Their moral ambiguity is whether the chaos they unleash is curative or just a different, more violent form of disease. The detective isn't a surgeon; they're a fever.

Martin Cruz Smith's Arkady Renko series, starting with 'Gorky Park'. Renko is a Soviet militsiya investigator in the 1980s, trying to solve crimes within a system that is inherently criminal and doesn't want them solved. His morality is a quiet, stubborn form of rebellion. He follows facts where they lead, even when it implicates the State, making him an enemy of the very power structure he serves. His ambiguity lies in his survival tactics—how much does he compromise to stay alive and keep investigating? The answer is always 'just enough'.

Gillian Flynn's 'Sharp Objects' features journalist Camille Preaker returning to her hometown to report on murders. She's a self-harming addict to trauma, and her investigation is deeply entwined with her own abusive family history. Her professional detachment is nonexistent; she's using the case to psychologically dissect herself and her monstrous mother. The grayness is in her methodology—she becomes too close, too involved, and her pursuit of the story borders on self-destruction. The detective here is a wound trying to solve a crime, and the solution only deepens the scar.
