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 person 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 are perfect for fans of heart-warming Japanese titles such as Before the Coffee Gets Cold.
