I received an eARC of this novel so I could read and review it. Thank you for the opportunity.
This is an enjoyable cozy mystery, focused on a jewel robbery and a treasure hunt, centered around hints placed in an eccentric, long dead millionaire’s private archives and home. I do wish they had showed the cyphers and given the reader the opportunity to solve it along with the characters. Overall. Though, this is a book that mystery fans will enjoy, and it contains nothing inappropriate or objectionable for a middle school or high school reader.
