My Grandfather, the Master Detective by Masateru Konishi (Literary Mystery)

<Translated from Japanese by Louise Heal Kawai>

I loved this book — It was gentle, dispassionate, intellectually engaging, and full of human insight depicted through understated, yet beautiful prose.

Kaede is a young, somewhat reserved, woman who shares a love of mysteries and puzzles with her aging grandfather. While the grandfather is suffering from Lewy Body Dementia, he manages to maintain aspects of his intellect and personality amid the confusions and hallucinations of the disease. In fact, one of the things I enjoyed the most about the book was the way he could train his still sharp wits and experimental approach on his own internal thinking apparatus to discern reality from hallucination.

Kaede is slow to connect with others, but she begins to bond with a colleague and his friend over stories, particularly in the Mystery genre. There are four “puzzles” her companions discuss, and these she takes to her grandfather who happily solves them quickly and with a crisp elucidation of his analytic steps. And then there is the biggest — and most impactful — puzzle of all. One that affects Kaede directly.

There was so much that I loved about reading this book — the portrayal of everyday culture in Japan with the small practices of cooking, commuting, fashion, and politeinteraction; the interactions with a beloved but in many ways failing elderly relative; and the broad range of “classic” mystery stories ranging from the well-known (e.g. Agatha Christie, Ellery Queen) to those I hadn’t heard of (e.g. John Dickson Carr, Takeshi Setogawa) to more contemporary series I hadn’t thought of in ages (e.g. Harry Kemmelman). The reader becomes, along with the characters themselves, a connoisseur of the genre in the most delightful and absorbing way.

The book is an ode to storytelling, friendship, and self understanding — the writing (and translation) is detailed, deep, but never loud. I’m always so impressed with an author that can make me feel deeply without hitting me over the head with overly dramatic, world-ending crises. Most of life is filled with the personal — deeply felt, deeply meaningful, but not necessarily attention grabbing calamities.

Thank you to G. P. Putnam’s Sons and NetGalley for providing an advance copy of this book in exchange for my honest review. The book will be published on March 17th, 2026.
