A vault sealed at 6 PM. A fortune gone by morning. The timer says the door never opened.

I created a short animated noir mystery called "The Vault That Never Opened." It's a fair-play puzzle — all the clues are in the video, and you can solve it if you pay attention.

Would love to hear if you figure out who did it before the reveal.

Any feedback is welcome.

I read a book where the protagonist is solving a case and a clue takes him to a remote town in Canada where he teams up with a female moutie to find the lair. She gets snowmobiles and they set out on the hunt. The bad guys see them coming and a running battle ensues. The mountie get chased and goes off a cliff. The protagonist is captured but it let go on foot and given a head start. He mountie dies not die as assumed but comes to save the day. What book is this?

Long-time whodunit reader here — Christie, Sayers, Chesterton, modern stuff like Horowitz and Osman. A few months back I started missing the feeling of cracking a case the way the books let you do it: clues, suspects, a real solution.

So I built one. deduce.studio — free daily detective puzzle in the browser. New case every day. You get clues, a suspect list, and the satisfying click when the pieces line up. No app, no signup, no ads.

It's solo-built (day job + 3 kids), runs on a home server for basically R0/month. Spirit of golden-age: fair-play clues, no leaps of logic.

Would genuinely love whodunit readers' eyes on it — am I hitting the genre or missing it? What would a Christie fan want sharper?

(Disclosure: I built this. Posting because the sub's theme says video games count and this is genre-native.)

When I was younger, I used t go onto the family-friendly Mystery.Net site, where ther were interactive whodunit games under the franchiae of Harry and Amy Silver, the titular cop and his intuitive daughter who solved mysteries, mostly murders, together. Does anyone know what I'm talking about? If so, since the site's been closed down, are there other resources?

We all know the most famous whodunit films such as The Silencf of the Lambs ; Clue ; Usual Suspects etc.

But what are, in your opinion, some lesser-known films that you think deserve more attention?

If you like reading or watching whodunit fiction, what about taking part in a whodunit investigation yourself (or be the killer).
