The mystery shares space with the moral learned by Abbie Jane that ""being different didn't make much difference..."" a sentiment that describes the affliction of this story, i.e.: people, setting and a treasure different from the usual don't make much of a difference to this ordinary, predictable mystery. Abbie Jane and her brother Eric belong to a family which is ""arty"" -- Daddy wears a beard, Mom dresses in dungarees and serves up slightly irregular meals, both have decided to escape the business world to set up an Indian relic store in Maine. When an unusual bear's tooth necklace is snitched at about the same time that the Indian boy Tim Neptune runs away, the two children join forces with Tim's younger brother and sister to track down the missing artifact and person. Alert readers will arrive at the telegraphed solution very quickly--much faster, in fact, that the junior detectives.
