There used to be a café 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...Her
Grandfather had been a core member of the Club. Coffee always tasted better with a good
old-fashioned mystery. As a lover of classic crime stories it's perhaps no surprise that
27-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. From
impossible locked room murders to confounding missing person cases the granddaughter and
grandfather team ?weave stories' in master-and-apprentice fashion to get to the bottom of a
variety of cases. All the while a shadow slowly closes in on Kaede posing a more insidious
threat... Steeped in references to classic crime from Christie to Chesterton to Poe My
Grandfather the Master Detective playfully nods to forebears of the genre while also carrying
the light-hearted escapist hallmarks of cosy crime books which have recently captured readers'
imaginations. Meanwhile its charming characters and affectionate focus on relationships bring
to mind heart-warming Japanese titles such as Before the Coffee Gets Cold.
