Perfect for you if...

You love traditional British detective fiction where the puzzle matters as much as the psychology of the suspects.
You're watching the Bertie Carvel Dalgliesh series and want to experience the source material that inspired it.
You appreciate crime novels where institutional secrets and professional rivalries create the real tension.

Maybe not for you if...

You prefer fast-paced thrillers with constant action over careful, methodical investigation.
You want a detective who's straightforward and likeable rather than introspective and complicated.
You're looking for modern forensic crime fiction with cutting-edge science details.

About this book

A forensic scientist is found murdered in his laboratory, and Scotland Yard is called to investigate. The victim was a well-respected member of the scientific community, but was disliked by those who worked closest to him, leaving detectives with numerous suspects and motives. Inspector Adam Dalgliesh is assigned to the case. He must navigate the lies, cover-ups, hidden agendas, and institutional secrecy surrounding the laboratory to uncover the truth. The investigation reveals dark secrets within the victim's workplace and explores the psychological dimensions of the crime.
