Sisi, the Empress of Austria, is missing. Did she slip away from court or was she taken. Only her diary remains and Emperor Franz turns to you for help. You are a traveling merchant of mysteries and puzzle books, the rare reader who can unlock the secrets between these lines. 

Follow a living trail through Schönbrunn as each solved riddle opens a fresh diary page and points you onward. Decode cryptic entries, catch a short melody to form a code, spot hidden details in stone and water, and piece together images that reveal the next step. 

Your path winds through quiet groves and fountains, past the palace, and up to the Gloriette where one of the best views in Vienna spreads out below. Find Sisi’s truth, aid Franz, and turn a royal garden into your own story.
