Djinn Patrol on the Purple Line

I can't believe this book won the 2022 Edgar Award for best Novel!!! There is hardly any mystery at all, the detective work is carried out by a couple of 7 year kids, Indian to English translation was bad and book should have had some explanations as to what many of the Indian words used in the book means! Main point is this book should have be promoted as a YA or Children's book! David N.
