Detective Kaga Series
Detective Kyoichiro Kaga is Higashino's other great detective — a thoughtful, persistent investigator who relies on deep psychological insight rather than forensic science. Kaga is a former high school teacher turned detective, which gives him a unique ability to understand people's hidden motivations. Warm, empathetic, and relentless, he is beloved by readers worldwide.
Higashino wrote 10 Kaga novels in total; the four listed below are available in English translation. Additional works remain available only in Japanese.
1998
Malice
The novel that introduced Detective Kyoichiro Kaga. A bestselling novelist is found murdered in his locked study. The prime suspect confesses immediately — but Kaga suspects the truth is far more twisted. A brilliant psychological puzzle told through multiple unreliable narratives that redefine the mystery genre.

A Death in Tokyo
A man is stabbed near the iconic Nihonbashi bridge and dies in the hospital without revealing his identity. The only clue is a single ticket for a ride he never took. Kaga investigates a case that spans decades, uncovering a tragic family history. A deep exploration of memory, grief, and justice.

Reading Order
Like the Galileo series, the Kaga novels are best enjoyed in publication order to appreciate the development of the protagonist:
- Malice (1998) — Kaga's debut. A stunning psychological mystery.
- Newcomer (2009) — Shows Kaga in a new light, working in a new precinct.
- A Death in Tokyo (Originally 2004 in Japan, but translated after Newcomer) — Kaga's most emotional case.
- The Final Curtain (2019) — The series conclusion in English.
Note: English publication order differs from Japanese publication order. A Death in Tokyo was originally published in Japanese in 2004 (between Malice and Newcomer in the series chronology) but translated later. For chronological story order within Kaga's personal arc, read it after Newcomer and before The Final Curtain.
