Fun, at home, date night game.
Made for a great, at home, date event. Hubby and I spent about 4 hours total (Part 1 on Saturday night, Part 2 on Sunday night) solving this murder. We've used similar games before, first time buying from Cryptic Killers. Will definitely purchase another one. Was challenging and fun!

Fun one!
My partner and I (both in our early 30s) enjoy doing these sorts of murder mystery packages together for date nights, and this was our first "Cryptic Killers" box. We really enjoyed it! The story was fun and I liked the mix of some puzzles with a lot of logical thinking and piecing things together. We talked through a lot of stuff together, which is always fun when you're doing these as a pair/group. We also thought everything was fair -- no wide leaps in logic or any guessing games were needed on our end. Everything made sense when we connected the right clues together. The documents were also well-made overall (some typos here and there, but nothing major) and high-quality. We read through everything and this ended up taking us a few hours over a couple of nights, so it was totally worth the money. The ONLY thing is we would have loved it if it was all on paper with no real online elements -- this game has a few online clues/pieces of evidence and we didn't have a laptop with us when we did it, so we were having to read them on our phones. It wasn't a huge deal, and mostly a personal preference. We'll be getting more of these in the future for sure!

Challenging and fun!
Hours of fun. Challenging. Didn't need to use any hints but it was close! Would definitely buy another one to solve.

Fun but take some time.
Be sure to read everything! Take notes. They are not that easy but they give hints if you are really stuck. I worked on it for ann hour and then finished the next day. I wouldn’t recommend for more than two people. Otherwise fun.

Fantastic mystery
Why did you pick this product vs others?: These are our hands down favorite brand of crime scene mysteries. This is our 2nd favorite; the first being Murder at Merivale Manor. This mystery required deciphering coded messages. Internet is needed for extra evidence. There is a play on words a few times that’s fun. There are hints if one gets stuck, but we live to go back after we finish to see if there was a clue or interpretation we didn’t consider. Always so much fun. Lots of cool evidence and the story eventually all comes together. Few hours of fantastic family fun that really lets everyone participate. Most times there is some sort of decoding to be done which we love. Consistently great mysteries with great stories, great clues that are just challenging enough to put together, and great characters. Very well written and always all the information one needs to solve the mystery. We have 6 who play together, 2 adults & 4 18 year olds.

Good Game for Detail-oriented Puzzlers
I was amazed at the details & quality put into this game! It was pretty challenging & I got at least 4 hours' worth of entertainment out of it. There's a lot of reading and a cryptogram involved, so if you don't mind all that, you'll probably love it!

Good challenging mysteries. Not completely obvious and a good brain-teasing alternative for date night. 3-4 hours of mystery solving involved. Ordered 1 and then ordered more. Shared them out with the fam too - hope to do one at the next family games night.

Super fun. Well thought out. Engaging and actually makes you think and collaborate with your fellow detectives. Pay attention! Details matter. Will definitely play again.

Brilliant. Single player, played over a few small sessions over 2 weeks. Great story. Satisfying to solve. Works out well. Have bought another. (Found a poly-pocket book useful for evidence and took notes as went along),

If you ever played game of this sort you will be heavily dissapointed. The case file consists only of 2 folders with paper hints, nothing much else. The riddle is written very poorly, and the main difficulty is not in solving it but undertanding what the creator had in mind. I agree with other people being dissapointed in the clues not leading you in an organised way to a conclusion - after all you have only 2 tasks. Only will give one extra star for the print quality, as it wasnt bad at all, but its only because it wasnt terrible. Will definitely not buy any more games from this author as its very dissapointing - 'detective for a day' stories are much much better.
