James Smelly Kelly used his super-senses and intelligence to make sure that the New York City subway in the 1930s ran safely throughout his lifetime and beyond.

James Kelly smelled EVERYTHING: rats in the shed; circus elephants a mile away; tomorrow's rain. His sense of smell was EXTRAORDINARY. But what good was a powerful nose? How could his super-sniffer make him special? In the New York City subway, James found his calling--and earned the nickname Smelly Kelly. Armed with his super-sniffer and the tools he invented, he tracked down leaks from the dangerous to the disgusting, from the comical to the bizarre. Then, he sprang into action to prevent cave-ins and explosions in the tunnels beneath the city. Smelly Kelly not only hunted leaks but also saved lives--and he discovered the truly extraordinary power inside him. Beth Anderson's fast-paced text and Jenn Harney's comical illustrations bring to life this everyday superhero.
