Looking for a Gritty Crime Novel with an Anti-Hero Protagonist

Hello,

I'm looking for a book with a main protagonist who is an anti-hero, not your typical good guy. I enjoy exaggerated gangster stories with strong character work. I'm a huge fan of anything by Guy Ritchie and Quentin Tarantino, and I absolutely adored Peaky Blinders. My favorite films include The Gentlemen and Once Upon a Time in Hollywood, especially characters like Ray (Charlie Hunnam) and Cliff Booth (Brad Pitt) – calm, competent, and quietly dangerous.

I've read The Godfather, The Sicilian, and The Last Don by Mario Puzo and loved all of them. I also read The Count of Monte Cristo, which is probably the best book I've ever read. I enjoy stories with revenge, manipulation, long-term schemes, or criminal underworlds.

Someone once recommended The First Law trilogy to me (which I found in a similar thread online), and while I gave it a shot, it felt a bit too weird or fantasy-heavy for my taste. I'm now looking for something a bit more grounded in reality, ideally contemporary or historical crime fiction.

I also love James Bond as a character, but unfortunately, I haven’t been able to find any of the Ian Fleming novels in my country.

I'm looking for:
– A main character who is morally ambiguous or an anti-hero
– Strong focus on scheming, power plays, or criminal activity
– Plenty of action or tension
– Bonus if it's from the perspective of a gangster or criminal figure

Any recommendations would be greatly appreciated! Thanks!
