Summer vacation turns into a real-life mystery tale for a teen detective

Fourteen-year-old Phoebe Hecht is slowly making her way through the long boring days of summer vacation. It doesn’t help that her mom’s marriage to a wealthy heart surgeon means that they’ve left their old, comfortable lives behind – so much so that her mom now seems ashamed at the merest mention of their humble beginnings. Now they live in a fancy Toronto neighborhood where she doesn’t belong, and the only friend she made at her new school, Yuri Kimura, has gone to Tokyo for the summer. The only thing getting Pheobe through the summer is her obsession with Agatha Christie mysteries and her covert spying on Colin, her crush who works at the local grocery store.

A chance meeting with a kind elderly neighbor named Mrs. Tomblin changes everything and brings all Phoebe’s interests together. When Mrs. Tomblin is robbed and assaulted she can’t remember anything about what happened, due to the fact that she is in the early stages of dementia. It is up to Phoebe and Colin to try and solve the mystery of the robbery. Could Mrs. Tomblin’s collection of old photographs be at the centre of the puzzle?
