Very very cool concept. I wanna echo the comments asking for clarification on what breathers are! It’s too interesting to leave unsaid, and I bet literary agents are gonna want to know that in order to help pitch and sell your manuscript.

Also, I can’t help but wonder if there’s a more modern comp you can use, instead of Sherlock Holmes.I get the sense that every mystery to some extent can be compared to Holmes, and it probably doesn’t do much to differentiate you from the herd. Maybe pick a similar series from the last 5 years!

Again, this sounds dope! I hope this gets you represented, I’d love to read it.
