Detective Kaga Series

Detective Kyoichiro Kaga is a thoughtful, persistent investigator who relies on psychological insight rather than scientific spectacle. A former teacher, he pays close attention to the histories and relationships that surround a crime.

The Japanese Kaga series began with Graduation in 1986. Macmillan's English series currently lists the four novels below, which are not the first four Japanese appearances. Publication details were last checked July 29, 2026.

Malice
1996

Malice

Originally published: 1996 (Japanese)
English edition: 2014
Translator: Alexander O. Smith

A bestselling novelist is found murdered in a locked house. The investigation soon identifies a killer, but Kaga is not satisfied with the apparent motive. The novel unfolds through competing written accounts.

Newcomer
2009

Newcomer

Originally published: 2009 (Japanese)
English edition: 2018
Translator: Giles Murray

A woman is found strangled in her apartment in Tokyo's Nihonbashi district. Kaga, newly transferred to the area, approaches the case by walking the neighborhood and talking to everyone — shopkeepers, delivery people, neighbors. A unique, character-driven mystery that reveals a community's hidden connections.

A Death in Tokyo
2011

A Death in Tokyo

Originally published: 2011 (Japanese)
English edition: 2022
Translator: Giles Murray

A wounded man reaches Tokyo's Nihonbashi Bridge before collapsing beneath its kirin statue. Kaga must determine where the attack occurred and why the victim used his final strength to reach that place.

The Final Curtain
2013

The Final Curtain

Originally published: 2013 (Japanese)
English edition: 2023
Translator: Giles Murray

A woman's murder in Tokyo becomes connected to another death and to the long-unanswered story of Kaga's mother. The fourth English-translated Kaga novel brings a deeply personal thread to its conclusion.

Reading Order

For the four official English translations, this publication order is the clearest path:

  1. Malice (1996) — The first Kaga novel translated into English.
  2. Newcomer (2009) — Shows Kaga in a new light, working in a new precinct.
  3. A Death in Tokyo (2011) — A public murder at Nihonbashi Bridge.
  4. The Final Curtain (2013) — A case tied to Kaga's family history.

This is an English-language reading path, not the complete Japanese publication order. Readers who want every Kaga appearance should begin with Graduation in Japanese.
