In this series, a brother, sister, and best friend are members of a club, the Spotlighters, who consider themselves detectives.  They’ve had some experience in solving mysteries and work well together.  The story doesn’t say how old they are, but middle school age seems to fit by their actions.  In this episode, there was a famous artist who had lived in their town.  He loved puzzles and riddles and had left clues for his only daughter to find his treasures.  Unfortunately, she died young and the mystery was left unsolved.  With nothing to go on except the daughter’s diary, the Spotlighters put together the clues to piece it together.  There is some conflict with the ancestors of this artist not cooperating, and the possibility of ghosts in the cemetery, but the three friends test their various theories.  I enjoyed this book because it seemed to fill a need for students who read at a lower level than what their age would indicate.  The cover art of the book shows older kids, not young kids, which would also appeal to middle-schoolers.  The characters are believable and resourceful and the dialog is appropriate.  The story moves quickly and kids won’t get bored.  This would be a great addition to both elementary and middle school libraries.
