Frequently Asked Questions

What is Mystery in the City?

Mystery in the City is a Paris-based company offering immersive experiences in the form of postcard packs. Our goal is to help city dwellers and city lovers have fun while learning about the people, places and history that have shaped the cities we love. Join our community of curious explorers and discover the hidden side of the world’s cities! Each postcard pack features 5 original illustrations created by local artists.

Our first postcard pack is focused on the city of Paris. Whether you’re a Paris lover or you just love a good puzzle challenge, this pack has something for you!

Where do your postcards come from?

Our postcards feature illustrations created by local artists who receive royalties from every sale​. Our postcard packs are shipped worldwide from Paris, France.

How do your puzzles work?

The challenges in your pack include logic puzzles, hidden object puzzles, word puzzles, video city hunts and more! Have fun while learning about the people, places and events that have shaped Paris. We provide clues for each puzzle. If you’re still stuck, then you can view the solution to an individual puzzle without spoiling the other challenges in your pack.

Who is this for? Is there a minimum age for your puzzles?

Our puzzles are designed for adults and children over the age of 15. Younger children can participate, but the activities are not specifically adapted for them and they may find them too difficult.

Can I send one of the postcards to someone else?

Our postcards (and puzzles) are meant to be shared! Feel free to share the adventure with your favorite francophile or puzzle lover. You can even solve the puzzles together if you’d like!

What if I want to purchase a postcard pack as a gift?

A Mystery in the City postcard pack makes a great gift because it offers the chance to share a fun experience with the gift recipient. Once you’ve completed your order, you will receive an email inviting you to specify any personalized message or special delivery instructions related to your gift.

What is your refund policy?

We sincerely hope that you love your postcard pack. If for any reason you are unsatisfied with your postcards, please email us at and we will do our best to make things right. We accept the return of unused and undamaged products for a full refund, less the original shipping fees, in the form of the original payment.

Do you offer postcard packs for other cities?
