Praise for "Who Could That Be at This Hour?":
"A Pink Panther-esque page turner...exceptionally literary and entirely singular. Characterized by linguistic playfulness and an appreciation for the archaic, "Who Could That Be at This Hour?" is frequently laugh-out-loud hilarious...illustrations by celebrated cartoonist Seth only add to the throwback gumshoe vibe of this outrageous, long-overdue, middle-grade follow-up series from a truly beloved narrator."—Los Angeles Times
* "Will thrill fans of the author's earlier works and have even reluctant readers turning pages with the fervor of seasoned bookworms. A must-have."—School Library Journal, starred review
"Demands to be read twice: once for the laughs and the second time for the clues."—The Boston Globe
