This is the review of Mystery Box Case 203 THE CURE.

The mystery comes in an envelope. The only things written on it are the Sleuth Kings P.O. box address and the case that you will be working on.

The epilogue is included and separated in another envelope.

To begin with your adventure, you need to login to their website and send Sullivan an email.

The files are neatly arranged in a white folder, with Sleuth Kings branding in front. All the files are organized inside the folder and they are even separated by paper clips.

Everything in my box!

The case objective is written on a card. We have to Find the Cure for Celest!

It also lists the contents of the case file: investigation instructions, investigation reports, clues, map, and more.

Here’s the snuck-out letter from Celest St. Claire. We can use her help in solving this case by taking a look at the information on her website.

The investigation instruction sheet names the client, the case you will be working on, and the whole situation. Our client for this case is Celest St. Claire.

These sheets provide a bunch of information that will help you understand the case. Read the letter thoroughly, and get the investigation going.

In this case, we just need to know the cure or at least acquire essential information about the drug that might help doctors to come up with the medicine for Celest.

This clue analysis section helps us to further understand all the given hints and evidences to solve the case.

The first clue we received was a little shady, but there are two things that really stand out. First is the random symbols beneath the WILD RAVE word and the zombie hands with varying numbers of fingers at the bottom of the sheet.

For our second clue, we have a menu with corresponding prices.

I’m quite sure that the message has something to do with the prices and its corresponding letters, as discussed on the notes written at the side of the menu.

The third clue is an Exercise Chart. Included in this sheet are the 15 different kinds of undead workout poses. What’s most noticeable about the poses are the numbers and unique titles for each.

The fourth clue features a long poem that is entitled A Grave Visit.

There are symbols beside the lines in the poem, which points us to a word or letter in their corresponding lines.

We also received the Woodland Cemetery Map. It lists the points of interest, as well as the words “come home to me”.

Another clue is a wanted poster of Craig Dulgar, the seller and distributor of illegal drugs. Together with his picture are some important details such as his age, height, weight, build, and more!

Featured at the back of the card are some random letters where you can find more clues to solve the mystery.

We also received a black button-type pin that features a zombie arm pointing at the letter C.

After solving the case, we can finally open the Epilogue envelope. Inside is a letter from Celest telling us that antidote we found was safe to take and there is actually enough number to give to the other victims.

It’s another mystery solved! We encountered Celest St. Claire again, and this time we helped find an antidote! As always, we enjoyed working on this mystery box. It’s extremely thrilling as we tried to decipher the clues they provided, and it’s also fulfilling when we finally reached the end. The recurring characters in this subscription make the stories seem like they’re connected to each other and that adds to the overall excitement as well. If you love decoding clues and solving mysteries, this subscription would be a great way to challenge yourself!
