"Mild-mannered James Kelly had a keen sense of smell, but what good was an 'extraordinary nose'—a superpower, really—when what he needed was to sniff out a new job in New York City? Anderson’s lively telling of a little-known story (who ever knew there was a heroic leak-smelling detective in the 1930s who saved the city with his nose?) employs strong, active verbs, as any superhero tale does, and is effectively complemented by digital illustrations that bring to life Kelly’s subterranean realm—the blue-black subway, the greenish miasmic smells drifting along, and Smelly Kelly’s red hair, a beacon in the darkness." —The Horn Book

"A tribute to the New York City subway’s first official 'leak detective.' Gifted with a literal nose for trouble, James Kelly arrived in New York from Ireland 'with nothing but a suitcase and a keen sense of smell'—and leveraged the latter into a long career over the first half of the 20th century sniffing out dangerous gas, water, steam, and other leaks in the subway system and elsewhere. Anderson casts him in a heroic mold, as he had not only a special ability, but the inner motivation to use it in service to public safety. Depicted with a confident smile and a mop of bright orange hair, Kelly shines as he goes after suggestive twists and curls of miasmic yellowish green in the illustrations’ succession of antique-looking street scenes and cross-sectional views of underground pipes and tunnels. Another immigrant gets the job done." — Kirkus Reviews

"This picture book biography centers on James Kelly, a white Irish immigrant and Transit Authority worker born in 1898, who used his incredible sense of smell to solve problems. Recommended for elementary collections, particularly those that emphasize makerspaces, problem-solving, or STEAM activities." —School Library Journal
