Kid Caramel, Private Investigator: Case of the Missing Ankh (Book 1) by Dwayne J. Ferguson

Kid Caramel, "Private Investigator" and his friend Earnest are visiting the art museum. Just after African Prince Abdu's elaborate film to introduce the Crystal Ankh is over, a smoke bomb explodes and the ancient treasure vanishes. The police cooperate with the junior detectives and lure the thief out of hiding with the announcement that the stolen Ankh was a fake. The public is invited to view the "real thing" (which is actually a chocolate creation made by Earnie's aunt, a candy maker). This smoothly paced, easy read should appeal to any child who loves a mystery.
