Kyle and Jenny are secret agents...in training.
That training takes place ad the Montgomery Junior Spy School, "one of the most prestigious spy schools in the country". Of course, I have no idea how many spy school are actually in the country so I do not have a number on how many are considered prestigious but taking the word of the author, Montgomery is one of them.
It is interesting that we only have the first names for either of these kids, or any of the other students they will join in training. Perhaps this is for security purposes, especially for the unnamed parents. Or maybe it is just because it really is not necessary to know what they are.
We meet both these twelve-year-old youngsters as they head to that facility on their first day, both excited about the chance to become true operatives. They have known each other virtually their whole lives, living next door to each other and always attending the same school. Jenny would readily admit to Kyle being her best friend. Kyle would agree if pressed.
While it is not possible to say which of them were more excited inside, Kyle is most definitely the more vocal of the two and the one more certain he was about to "pass spy school with flying colors"; he felt he was certain to because both his parents were spies for many years and had been training him his whole life, he felt. Not unexpectedly, brash and somewhat cocky Kyle is about to get a rude awakening.
Joining the two in their training, among the many others in this year's class, is another kid who hits it off well with them from the beginning, Paul. Together the three help each other because better than they thought they could be; good enough to actually become the spies they wanted to be.
