The Final Curtain by Keigo Higashino

The Final Curtain (Kyoichiro Kaga, #4)

by Keigo Higashino

A decade ago, Tokyo Police Detective Kyoichiro Kaga went to collect the ashes of his recently deceased mother. Years before, she ran away from her husband and son without explanation or any further contact, only to die alone in an apartment far away, leaving her estranged son with many unanswered questions.

Now in Tokyo, Michiko Oshitani is found dead many miles from home. Strangled to death, left in an empty apartment rented under a false name by a man who has disappeared without a trace. Oshitani lived far away in Sendai, with no known connection to Tokyo - and neither her family nor co-workers have any idea why she was there.

Hers is the second suspicious death in that part of Tokyo - the other was a homeless man, killed and his body burned in a tent by the river. As the police search through Oshitani's past for any clue that might shed some light, one of the detectives reaches out to Detective Kaga for advice. As the case unfolds an unexpected connection emerges between the shocking murders now and the long-ago secret life of Detective Kaga's missing mother.

The Final Curtain, one of Keigo Higashino's most acclaimed mysteries, brings the story of Detective Kaga to a surprising climax in a series of rich, surprising twists.

Plot Synopsis (as spoiler-free as I can get):

Called to help with the investigation of a strangulation case, Kaga is surprised to discover the victim is an old schoolmate of his. While he is investigating that murder, another murder happens, and he is surprised to find the two are connected. But there are few clues, and the one person who could have answers is not talking. It is up to Kaga to wade through decades of lies and misdirections to find out the answer. And in doing so, Kaga might finally get an explanation about the death of the mother who abandoned him decades earlier.

Main Characters

Instead of listing the main characters and giving my opinion, I will share my overall view of them. The Final Curtain didn’t have a set main character. The book flowed from one character to another. If I had to pick out three characters that stood out the most, they would be:

  • Kyoichiro Kaga
  • Shuhei Matsumiya
  • Hiromi Kadokura (Hiromi Asai)

These characters (well, all of the characters) were well-written and multi-faceted. I was surprised by this, seeing that this is the final book in this series and the first time I have read any book by this author. It was a pleasant surprise and added to my enjoyment of the book.

My review:

I didn’t know what to expect when I started reading The Final Curtain. I was a little iffy about it because it was book 10 in the series, and I figured I would have difficulty getting into it. Not in this case. My only complaint was that it was slow in spots. But, in my eyes, that slowness added to the overall ambiance of the book. It also allowed the author to build up the storyline and tie everything together without looking rushed.

The author did something clever at the beginning of the book. He added a cast of characters. I was thrilled that he did that. I usually go through my Kindle to find names while writing my review. I didn’t have to do that in this book.

The main storyline in The Final Curtain is centered around the murder investigation of Michiko Oshitani and the homeless man. The storyline was well-written and well-fleshed out. A few red herrings were thrown out that had me thinking that Kaga would never solve the mystery (the bridges angle was fascinating). The twist at the end and how the author tied everything together were well done. I was left shaking my head at who the killer was and why that person did what they did.

The end of The Final Curtain was a little bittersweet. I liked how the author brought everything together and wrapped up the storylines. I also liked that there was a finality to the storylines. Seeing that this is the end of the storyline, the author ends the book in a way that clarifies that there will be no more after.

Many thanks to St. Martin’s Press, Minotaur Books, NetGalley, Keigo Higashino, and Giles Murray for allowing me to read and review this ARC of The Final Curtain. All opinions stated in this review are mine.
