The Thumbprint Mysteries are written on the fourth-, sixth-, and eighth-grade levels for adults who want to read but whose reading skills are undeveloped. Written by ten well-known mystery writers, each suspense story has characters, situations, and concerns that challenge adult minds, yet are easy to read. This installment of ten new titles is written at a sixth-grade reading level.
Written at a lower reading level without sacrificing the suspense of adult-level mysteries
Because the series deals openly with adult themes and situations, it appeals to the adult reader with limited reading skills.
