Arrived so quickly and in perfect condition, a perfect stocking filler and I bought a second for myself!
I just put the first postcard in the mail to my granddaughter. I, of course, had to try to solve the mystery first. I did need at least the first clue, but thought it was great fun.
I can't wait for the feedback from my granddaughter!
These are really fun activities to do. They make you think out side of the box. Make sure to also get the Detective's Notes book. It adds to the fun!
Came really quickly! My parents loved the first one and begged me to send them more so I'm looking forward to sending them this one!
Excellent mystery as usual!! As soon as I saw this new mystery I knew I had to buy it. These postcard games are such a fantastic idea & are always really well thought out & executed. The design is beautiful. Really love this mystery & would highly recommend it to others. Thank you so much ❤️
