Goodreads Synopsis:

From the acclaimed author of Malice and Newcomer, a confounding murder in Tokyo is connected to the mystery of the disappearance and death of Detective Kaga’s own mother.

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 the bare 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 or friends have any idea why she would have gone there.

Hers is the second strangulation death in that approximate area 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 connective emerges between the murder (or murders) now and the long ago case of the missing mother of Detective Kaga.

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


First Line:

Despite decades having passed, Yasuyo Miyamoto could still recall that day with absolute clarity.

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.

Goodreads synopsis:

Detective Tracy Crosswhite has a skill, and a soft spot, for tackling unsolved crimes. Having lost her own sister to murder at a young age, Tracy has dedicated her career to bringing justice and closure to the families and friends of victims of crime.

So when Jenny, a former police academy classmate, and protégé, asks Tracy to help solve a cold case that involves the suspicious suicide of a Native American high school girl forty years earlier, Tracy agrees. Following up on evidence Jenny’s detective father collected when he was the investigating deputy, Tracy probes one small town’s memory and finds dark, well-concealed secrets hidden within the community’s fabric. Can Tracy uphold the promise she’s made to the dead girl’s family and deliver the truth of what happened to their daughter? Or will she become the next victim?


Want a book you can devour in one sitting? Then read In the Clearing. I was completely glued to this one and couldn’t put it down.

The main storyline and the subplot were both fantastic. The author does a great job of alternating between the cold case and the one Tracy is currently working on, seamlessly moving between past and present—and even between different perspectives. That’s something I usually struggle with in books like this, but here it absolutely worked. The way both cases come together in the end is chilling. I actually got goosebumps.

I did figure out who killed Kimi about halfway through the book—but not because it was obvious in a bad way. There were plenty of red herrings and apparent dead ends, so when everything was revealed, I was still shocked. And there’s a major twist I did not see coming.

What surprised me most is that even though this is part of a series, it works perfectly as a standalone. I usually avoid reading books out of order because characters and plots tend to bleed together. Not here. What happens in previous books stays in previous books.
