Sleuth Kings


Ready to work with a detective via email to solve cases and earn real-world rewards?

You've come to the right place.

Who we are:

Sleuth Kings provides monthly mysteries to your door. Each month we send out physical case files in the mail and offer you the opportunity to work with Sullivan King - our Lead Detective - via email in order to solve the cases and earn real-world rewards.

How it works:

Joining is easy - just check out this month's case and click subscribe. Once you enter your information, Sullivan will put together a case file and send it to you in the mail. After you receive it, you can send Sullivan an email to get started on your investigation. From there, you'll work together with Sullivan through every step of the case.


When the case is solved, you'll earn SK Reward Points you can exchange for physical prizes. There's no catch or cash involved: even shipping is free. Just save up your points and exchange them for what you want. We'll take care of the rest.

Subscribe before 10/31 to get this month's case.
