Eight-year-old Jacob Two-Two enlists the aid of his new neighbor, master spy X. Barnaby Dinglebat, when I. M. Greedyguts, the new headmaster at his school, makes the lives of the students miserable.

Things turn sour at Privilege House, Jacob Two-Two’s private school, when the headmaster, Mr. Goodbody, is replaced by the despicable I.M. Greedyguts.

Fortunately, Jacob has a new friend he can turn to for help: X. Barnaby Dinglebat, Master Spy.
