Puzzle / mystery (but not too tricky!) advent calendar

[PiratePenguin]

I'm after a puzzle / mystery advent calendar. Last year i did Professor Charlie's World Tour which was just the right level of difficulty. I've looked into some of the escape style ones, but they look really hard.
Has anyone done one in previous years that they would recommended?

Many thanks.

I got one last year for DS off Etsy- you pay for the download & then print at home & put into envelopes. Then I think you had to log the solution online at the end…
