Locked Room Mysteries - A List of Whodunnits

Inspired by Wake Up Dead Man (the newest Knives Out installment), I decided to make a list of Locked Room Mysteries.

Compiled based on personal interests and various blogs.

A classic, and very early, locked-room mystery is The Mystery of the Yellow Room by Gaston Leroux. Great list!

Oh, thank you!

I'm considering turning this list into a side quest, so I appreciate community feedback too!!

Yes it’s like the original locked room also would love this for a side quest.

It's definitely one of the earliest! I've got The Big Bow Mystery by Israel Zangwill, published 15 years prior to it, which is considered the first full length locked room mystery!

Love this idea for a side quest!!!

Thanks!

Drop of Corruption by Robert Jackson Bennett and The Library After Dark by Ande Pliego would fit well here I think!
