“Brain-teasing mysteries presented in something like a fairytale framework.” —Kirkus
Description:
from the publisher
A Japanese The Thursday Murder Club, taking healing fiction for a mystery-filled spin with this bestseller that has sold more than 200,000 copies in Japan.
He’s not your average Grandpa.
As a lover of classic crime stories, it’s no surprise that schoolteacher Kaede encounters everyday mysteries more often than your typical twenty-seven-year-old.
Solving them is another matter, though. For that, she turns to her beloved grandfather, who retains a keen sharpness of mind despite his dementia, and who was once a key member of The Waseda Mystery Club. From impossible locked room murders to confounding missing persons cases, the grandfather-granddaughter duo “weave stories” to get to the bottom of every mystery. But all the while, an insidious shadow from Kaede’s past slowly closes in on her . . .
Steeped in references to classic crime from Christie to Chesterton to Poe, My Grandfather, the Master Detective plays with the genre, capturing readers’ imagination in this Tokyo-set escapist mystery. Its charming characters and affectionate focus on relationships echo heartwarming Japanese titles such as Before the Coffee Gets Cold.
My thoughts:
This book offers an enjoyable read that features, as protagonists, a grandfather and granddaughter. Readers learn early on that the grandfather has been diagnosed with lewy body dementia. (It is important for the reader to know something about this condition but I felt that there may have been a bit more information given than a general reader might need.) The granddaughter visits regularly, cares deeply for him and shares his love of mysteries.
When a number of real life mysteries come to Kaede’s attention, she and two men whom she knows, try to solve them. Grandfather also helps. At the same time, something from Kaede’s past willl come up. How will this impact Kaede and the other characters? How will Kaede and her friends negotiate their relationships? Will there be a bit of romance?
Throughout these pages, there are references to many mystery novels. I enjoyed that aspect of this title.
I think that this book will be welcomed by those who have read Asian books such as Hot Chocolate on Thursday, and those who enjoyed other mysteries featuring at least one character of a “certain” age.
Many thanks to NetGalley and Putnam for this title. All opinions are my own.
Four stars ⭐⭐⭐⭐
