Sleuth Kings

Immerse yourself in an interactive monthly mystery. Receive a physical case file full of evidence, puzzles, ciphers, and more. Work hand-in-hand with Sullivan King, our lead detective, via email as you solve the case.

Each month’s case is a new, stand-alone mystery that takes approximately 2-3 hours to complete. After each case that you solve, you’ll also receive a follow-up letter from the client as well as a small gift. For every 4 cases you solve, you’ll be rewarded with a FREE bonus case that revolves around the hunt for Sullivan’s father.

    I love this box. It’s so much fun and has a great twist–you work directly with a detective to help him solve the cases. Customer service with this company is amazing. Such nice people. Such a great product. You really should try this box. I think you’d like it!
