About this tour

Step into a Parisian mystery on this immersive Palais-Royal investigation tour, where a costumed actor turns the neighborhood’s storied streets into a life-size case file. The story begins in 1841, after the body of Duchess Blanche of Condrie is discovered near the agency of famed detective Vidocq. The case was never solved, but a new investigator is ready to reopen it, and needs your help.

Follow the clues through the Palais-Royal district as you rediscover its iconic monuments and hear historical anecdotes along the way. The experience takes place entirely outdoors, so you can explore the neighborhood without entering monuments or museums. Meet opposite the entrance of Grand-Véfour at 75001 Paris, and join the investigation in French, guided by the costumed actor. A mobile ticket and entrance fee are included, and free cancellation is available.

How this score is calculated

This score is based on one provider. Viator rates it 5.00 from 4 reviews. We place that rating among all Viator ratings and weight it by its review count. If the tour is found on another provider later, both ratings are combined.

How the score works and rating distribution in Paris
  • Each provider rating is turned into a percentile: the share of that provider's ratings it beats, weighted by review counts.
  • Listings on different providers are combined in proportion to their review counts.
  • Tours with few reviews are pulled toward the average until more reviews come in, so a handful of perfect reviews can't top the list.
  • The result is shown from 0 to 10: this tour scores 7.3. Top 31% in Paris means it ranks in the top 31% of tours in Paris by this score.
