New Orleans French Quarter Yellow Fever Mystery Walk

It is August 1878, and yellow fever is turning the French Quarter into a graveyard. You are Louis Joseph Dufilho Jr., America's first licensed pharmacist, and a coded letter reaches your hands. Walk from the French Market to your apothecary on Chartres Street, decoding the secret hidden across the Quarter's iconic landmarks before the trail — and the city — are lost. Blending New Orleans history — the Ursuline nuns, the 1878 epidemic, the wrought-iron balconies of Royal and Bourbon Streets, the Cabildo and St. Louis Cathedral — with a gothic conspiracy thriller, every stop reveals the landmark's true story while advancing the intrigue. Augmented reality brings the clues to life, with audio narration in 32 languages. Start whenever you like, go at your own pace, pause for photos. No guide, no fixed schedule, no app to download — just open it on your phone and play. A perfect blend of sightseeing, storytelling and puzzles for explorers, couples and families visiting New Orleans.
