THE WORLD-FAMOUS NINE

Coded clues put two young sleuths on the trail of a magic mandala hidden somewhere in a huge, bustling department store.

Hardly has meek young Zander Olinga arrived for a visit with Zina Winebee, his grandmother and owner-manager of the Number Nine Plaza, than he learns of a threat to the continued existence of the renowned emporium. The danger is linked to Darkbloom, a rumored evil spirit set on reversing the good-fortune charm left by Nepali monks at the store’s founding. The stone tablet bearing the magical mandala vanished 90 years ago, and finding its hiding place becomes a race pitting Zander and intrepid new ally Natasha Novikov against unknown saboteurs whose minds have been taken over by Darkbloom. The keys to the tablet’s location are a series of ingenious word and number clues left by Zander’s great-granduncle Vladimir, and Guterson provides enough hints along the way for savvy readers to decode them. What he doesn’t do is give either his leads or the many-faceted store (which, over the course of the story, is explored from the Ferris wheel on its roof to the bakery in the cellar) any more depth or distinctive traits than he gives Nepali religious practice. Darkbloom remains a shadowy bugaboo, its actual nature and motivations unexplained and its fate left anticlimactically unresolved. Zander’s father is from Cameroon, and his mother reads white; names cue some diversity in the supporting cast. Final art not seen. (This review has been updated for factual accuracy.)

A whodunit that doesn’t live up to its intriguing premise.
