The heartwarming, award-winning Japanese sensation, My Grandfather, the Master Detective is an affectionate, cosy whodunit – and a story of living your days to the fullest. Perfect for fans of Before the Coffee Gets Cold.

There used to be a cafe called Mon Cheri at Nishi Waseda where members of the Waseda Mystery Club spent day after day frothing in excitement over the latest mystery novels, and now he and Kaede solve mysteries together . . .

As a lover of classic crime stories, it’s perhaps no surprise that twenty-seven-year-old schoolteacher Kaede encounters everyday mysteries more often than your average person. Solving them is another matter, though, and the person she always heads to for guidance is her beloved grandfather – who, despite having dementia, retains a keen sharpness of mind.
