Can you recommend the best police graphic novel?

Sure. 'The Maltese Falcon' by Dashiell Hammett is a great one. Sam Spade, the detective in the story, is a tough and shrewd character. Another is 'A is for Alibi' by Sue Grafton. It's the start of her Kinsey Millhone series, and it's full of mystery and suspense. And 'Presumed Innocent' by Scott Turow is also highly recommended.

For beginners, 'The No. 1 Ladies' Detective Agency' by Alexander McCall Smith is a great choice. It's a light - hearted and charming series set in Botswana with a female detective. Another good one is 'The Hound of the Baskervilles' by Arthur Conan Doyle. It's a classic mystery with Sherlock Holmes, who is often involved in police - like investigations. Also, 'A is for Alibi' by Sue Grafton is easy to get into. It's the start of a long series and has a good mystery for the private investigator (who often works with the police) to solve.

One of the best is 'Sin City' by Frank Miller. It has a noir - style atmosphere with complex police characters and gritty crime - fighting stories. The art is also very distinctive, with its high - contrast black - and - white panels that add to the moody feel.

Sure. 'Presumed Innocent' by Scott Turow is excellent. It's about a prosecutor who becomes the prime suspect in a murder case within his own office. It shows the inner workings of the legal and police systems in a very engaging way.

Sure. 'Gone, Baby, Gone' by Dennis Lehane. It has a gripping plot about a missing child. The story shows the moral and ethical dilemmas that police face during investigations.

Sure. 'The Black Echo' by Michael Connelly is a great one. It features detective Hieronymus 'Harry' Bosch. Connelly is known for his detailed police procedurals, and this book is no exception. Another is 'A is for Alibi' by Sue Grafton. Her Kinsey Millhone series has a female private investigator who often works closely with the police. And 'The Killing Floor' by Lee Child. While not strictly a police - only book, the main character Jack Reacher often gets involved with the police in solving crimes.

Well, 'The MP's Duty' is also a great military police novel. It delves deep into the daily tasks, moral dilemmas, and the unique camaraderie among military police. The story is full of action and suspense that keeps readers hooked from start to finish.

I would recommend the 'Kay Scarpetta' series. Dr. Scarpetta is a forensic pathologist who often works closely with the police in solving crimes. The novels are known for their detailed forensic science and the complex personality of Scarpetta. Also, the 'Charlie Parker' series by John Connolly. Parker is a private detective with a dark past, and the series has elements of the supernatural blended with police - style investigations.

Sure. 'The Girl with the Dragon Tattoo' by Stieg Larsson is a great one. It features a complex mystery and interesting characters, with a police - like figure in the form of Mikael Blomkvist who investigates some dark secrets. Another is 'In the Woods' by Tana French. It has a great police procedural aspect as detectives try to solve a mystery related to a child's disappearance. And 'Gone Girl' by Gillian Flynn also has elements of police work as they search for the missing Amy.

Sure. 'The No. 1 Ladies' Detective Agency' by Alexander McCall Smith is a great start. It has a gentle, engaging style and follows the investigations of a female detective in Botswana. It's not as dark and complex as some others, making it easy for beginners to get into. Another one is 'Blue Blood' by Edward Conlon. It gives a real - life view of police work in New York City in a relatively accessible way.
