During a visit to the mysterious castle of Casa Loma, Vivi and Simon find an old miniature camera. Could this little gem have belonged to a spy? Only the clues in the salvaged photos will be able to tell the tale.
And so begins a story that will take the young reader on an extraordinary urban mystery in Toronto.
