Humphrey is back in his tenth adventure in the beloved middle-grade series!
So many secrets are flying around Room 26 that Humphrey can barely keep track. Mrs. Brisbane knows a student is leaving, but Humphrey can't figure out which one. (Even more confusing, Mrs. Brisbane seems unsqueakably happy about it.) The class is studying the Ancient Egyptians, and some of the kids have made up secret clubs and secret codes. Even Aldo is holding back news from Humphrey.
Humphrey's job as classroom pet is to help his humans solve their problems, but all these secrets are making it HARD-HARD-HARD!
