If you like immersive storytelling, Jack the Ripper, and figuring out ciphers (hidden messages) then this puzzling immersive story in 12 chapters with an epilogue is for you. There are a few other unique puzzles too. I love Cosy Killer games.

This is my favorite subscription box game to date. Played over 12 months.It is beautifully written with great puzzles. Highly recommend. there is really nothing better than this, and I have played many other brands. There are some areas of difficulty, but not in every box. This is recommended for someone who has played more difficult box subscription games such as MPC or HAK.
