Sneak Peek

Master Detective Case 032: Two Ring Circus

Sullivan’s office has been ransacked and one thing is clear – the Moretti crime family is behind the break-in. The thieves were after a diamond and found one – just not the one they wanted. Instead, they stole a wedding ring that once belonged to Sullivan’s late mother. Worse, before they could sell the ring, they managed to lose it. Can you help Sullivan race against the Moretti family to get his mother’s ring back? Sign up today to find out!

Rookie Detective: Test of Courage

Sean Hart, along with several other students from Flyer High School, has gone missing. The police are working around the clock to find the students but, so far, have made little progress. Sullivan believes an abandoned house used by teenagers for a “test of courage” is somehow linked to the disappearances, but there’s a problem with his theory – the house is empty. Can you help Sullivan crack the mystery and bring the missing kids home before someone else vanishes?

Questions

Q: Do you need the Internet to solve the cases?Asked by Zayani M., June 2019

Hi Zayani,

Since you work with the detective via email, you do need an Internet connection as well as an email account. Some cases also include websites that you'll have to visit. That said, you will never need to use Google or any other web resource that isn't a part of the case.

Q: Is each month a case that can be solved without the next box? There is another subscription that is similar and you have to get 6 boxes to be able to solve the case.Asked by Shelly G., September 2019

Hi Shelly,

That's a great question - thank you for asking!

All of our cases are stand-alone, so you'll get a new, independent mystery to solve each month.

Q: I have a few questions. 1) do you ship to canada? 2) if so, how much is shipping? 3) if I want to send this as a gift, would I sign up as the subscriber or would account be in name of gift recipientAsked by Alexis S., January 2020

Hi Alexis,

Thanks for reaching out! Unfortunately, we're only able to ship within the US.

Q: One more...are the rookie detective kits based on the same story as the master detective kits, but with fewer puzzles? We have an 11yo and 8yo who enjoy these challenges. Which to get?Asked by Chris M., December 2019

Hi Chris,

That's a great question - thank you!

The Rookie Detective cases offer new stories that are different from the Master Detective cases.

I think the Rookie Detective cases would be a great fit for your 11 year old and 8 year old! They are designed to take around an hour or so to work through and all of the puzzles (except for the final one) can be solved independently of each other, which means they can work on separate puzzles if...

It's taken me too long to write a review, since I've been subscribed for so long now, but this is my favorite subscription box by far! I always have a great time trying to solve each month's case with family and friends, and the "interactive" element with Sullivan adds a fun immersive twist to the experience. Cases could probably be solved alone, but it's a lot of fun to work with others. I really like that some cases have callbacks to previously encountered characters or events, and that the puzzles and clues are always fresh and different. Sometimes the difficulty of the puzzles can vary from month to month, but there's a good hint system built into the box, and the team behind Sleuth Kings is very helpful and responsive. I was missing something in a box once and the issue was solved quickly and professionally. I also appreciate that if you're on a month-by-month plan you can skip a renewal if needed without otherwise adjusting your subscription. Overall, a fantastic experience that you should try if given the chance!!

My husband and I wanted an activity to do with our fourteen year old son. He loved and we loved it!! It was so much fun figure it out the clues and email the detective. The clues were challenging but not to the point of frustration. It took us two days to solve and we are excitedly waiting for our next case!

Just received my second box. I can’t tell you how fun these are. My husband and I love working through these. They challenge both of us. We will take breaks and then one of us will shout I think I know what to do. Really good bonding time for us.

Found them on FB. Started out with the FREE mystery, then purchased some archived cases and was immediately hooked! I love the uniqueness of Sleuth Kings, their whole concept is very different from the other companies. It's fun "working" with Sullivan to solve the cases, I feel like a real gumshoe. The stories are interesting, the puzzles vary in type and level of challenge, the clues/props are well done, high quality. It's easy to get helpful hints and customer service is outstanding! I also like that you can choose to subscribe to full or mini cases (or both!). I highly recommend Sleuth Kings!

These are simply silly. They are not really challenging, and are really rather cheesy.
It would be better suited for someone around age 11-12 .

Hi Hollie,

I appreciate your feedback. I apologize that you didn't enjoy your Sleuth Kings subscription. We do work hard to make the cases enjoyable for a wide array of people. Many do find the Master Detective cases challenging, however, I'm really sorry that the puzzles were too easy for you.

We do try to keep our cases family-friendly so that the content is fun for people of all ages - including kids. We also try to vary our puzzles month-to-month so that they stay fresh and offer different kinds of challenges with each case.

Thanks again for trying Sleuth Kings!

I’ve tried quite a few “mystery boxes” and Sleuth Kings’ definitely at the top. The stories are great and the puzzles are challenging and fun...if you ever need help Sully’s always there for you. The e-mail exchanges with Sullivan are what makes this box unique. We’ve gotten close enough where he doesn’t threaten violence when I call him Nancy Drew. Or Holmes. Or Sugar Britches. 10% of the fun is coming up with absurd nicknames for Sullivan.

If you like single box closure and intriguing stories this ones worth a try. I know I’m hooked. I just need to figure out my plan to work through all the archived cases. 😁

Mother/Daughter bonding time!

So this was our first mystery subscription and the experience has been terrific. I ordered one case just to try it out first; received the case quickly and Detective Sullivan was always quick with a reply to help when we asked for it. Signed up for the subscription and we completed the second case on our own. So there are varying levels of challenges, which is great to keep things different each time. The packages have been well made, complete, and very detailed. If you are looking for a new activity this is a great subscription to try.
