In Book #3 of Eddie Red Undercover, Edmund is back working for the New York City Police Department after a bomb was delivered to a police station with the note “1-Eddie will know what this means” attached. (1) “Last spring I worked for the NYPD because of my photographic memory and ability to draw almost perfect character sketches.” (2)  The police tell Edmund as little as possible in an attempt to protect him, but Edmund and his friend Jonah realize this case is  dangerous because they have assigned a body guard for Edmund. The police have also put Detective Bovano undercover as a teacher in Edmund’s expansive private middle school- Senate. Det. Bovano is in every class with Edmund using the name Mr. Frank, but this is OK with them because Mr. Frank is a better chemistry teacher than their regular chemistry teacher.  Jonah and Edmund keep working the clues, but which items are clues and which are not? Are some items just coincidence? Are they working one case or two?         As the plot unravels, it is revealed the villain actually had five bombs planted throughout the city. While Jonah and Edmund are using the computers at the public library, Edmund receives a text from an unknown someone saying, ” You’re looking in the wrong place… The answer is on the map. Gold. Stolen treasure. ”  Jonah and Edmund try to decode the clues and solve the case without Bovano because once they tell Bovano, Edmund will be off the case.   In the meantime, Senate Middle School is having a school carnival which the boys are working. While there, Edmund finally gets some alone time with a particular girl as they go into the “Maze”. The villain kidnaps Edmund from inside the “Maze” wanting his memory and art ability to sketch the basement of the art museum to be used in a future museum robbery. Jonah uses a clue from Edmund to locate his whereabouts and has the Senate Middle School marching band parade down the street outside the hotel where Edmund is being held as a diversion. Then, Edmund uses the birthday gift Jonah gave him , a mace pen, to get away from his kidnapper. Bovano arrests the villain Lars at the airport at the same time the unknown texter sends Edmund the text, ” ‘ You ruined everything.’ ”  (184) “THE END”
