The Great Trouble

**The suspenseful tale of two courageous kids and one inquisitive scientist who teamed up to stop an epidemic. “A delightful combination of race-against-the-clock medical mystery and outwit-the-bad-guys adventure.”** —Publishers Weekly, Starred Eel has troubles of his own: As an orphan and a “mudlark,” he spends his days in the filthy River Thames, searching for bits of things to sell. He’s being hunted by Fisheye Bill Tyler, and a nastier man never walked the streets of London. And he’s got a secret that costs him four precious shillings a week to keep safe. But even for Eel, things aren’t so bad until that fateful August day in 1854—the day the deadly cholera epidemic (“blue death”) comes to Broad Street. Everyone believes that cholera is spread through poisonous air. But one man, Dr. John Snow, has a different theory. As the epidemic surges, it’s up to Eel and his best friend, Florrie, to gather evidence to prove Dr. Snow’s theory—before the entire neighborhood is wiped out. “Hopkinson illuminates a pivotal chapter in the history of public health. . . . Accessible . . . and entertaining.” —School Library Journal, Starred “For [readers] who love suspense, drama, and mystery.” —TIME for Kids
