You are retired from the spy game (see Escape Rooms 4-7 https://torontopubliclibrary.typepad.com/teens/online-escape-rooms.html) and have been living under an assumed name for almost a year. Your former life as a spy now seems like a distant memory, replaced by living in a small town where everyone knows you as the new postal worker. Days now are simple - get up early, sort and deliver the mail, then return home to catch up on all the shows you missed while working for INTERPOL.

One day, you are sorting the mail when you find an envelope addressed to you - not your new identity, but your real name. Inside the envelope you find three things: a letter, a piece of a torn book cover and a riddle.
