"Devin Cooper has some pretty unlucky neighbors. The up-and-coming Ekat agent hones his skills by building tree-house fortresses in his backyard. His security systems outmatch those of some banks, which is a problem for anyone who accidentally gets too close. (Devin's parents won't let him keep "trespassers" in his underground prison, but they ignore his water-balloon cannon.) However, Devin's neighbors will get a break when he goes to the Ekat stronghold in Cairo for a few weeks. The leadership has asked him to design booby traps to protect the Ekat Clues around the world, starting with an item that's rumored to be hidden inside the British museum.
