EEK-EEK-EEK Mrs. Brisbane is missing Humphrey has always investigated things, like why Speak-Up-Sayeh was so quiet and Tall-Paul and Small-Paul didn't get along, but this is a true mystery--Mrs. Brisbane is missing. She just didn't show up in Room 26 one morning and no one told Humphrey why. The class has a substitute teacher, called Mr. E., but he's no Mrs. Brisbane. Humphrey has just learned about Sherlock Holmes, so he vows to be just as SMART-SMART-SMART about collecting clues and following leads to solve the mystery of Mrs. Brisbane (and a few others along the way).
