The Secret of High Park

A brass key. A secret riddle. A race across Toronto.

When Aidan’s sneaker catches on a loose stone in High Park, he and his dad, Zach, uncover a mystery more than a century old — a brass key, a riddle that must be solved by noon, and a stranger in a green coat who wants the prize for himself.

From historic Colborne Lodge to the steam engines of Roundhouse Park and the old lighthouse on the Toronto Islands, the father-and-son Toronto Mystery Duo must follow the clues, outsmart a thief, and bring home a treasure the city forgot.

Told in bold, full-colour comic panels, this fast-moving mystery is perfect for young detectives ages 6 to 10 — and a great read-together adventure for parents and kids who love maps, riddles, and hidden history in real places.
