Set in the town of Toresal in the kingdom of Miradania, Secret Letter is an adventure about a fourteen year old orphan that everyone knows as "Jack". Jack is pulled into a dangerous mystery when a handful of Baron Fossville's mercenaries begin hunting him. From Grubber's Market through Commerce Street, and onto Lord's Keep; Jack is faced with numerous challenges. Teisha lends a hand along the way, as does Bobby, the mysterious boy always lurking in Lord's Market. The ladies at Maiden House are helpful, but can sometimes be a bit overbearing. The shopkeepers are always willing to chat about the latest gossip. Jack, he just wants to sit down and eat an apple.
