This classic whodunit by the nineteenth-century author of The Leavenworth Case introduces the original spinster sleuth: Amelia Butterworth.Living alone in the moneyed Manhattan neighborhood of Gramercy Park, Amelia Butterworth is happy to keep to herself. But awakened one night by the sound of a horse-drawn cab outside her mansion, she spies a curious couple entering a home she knows to be empty. When only the man emerges, Amelia calls the police—and is suddenly the sole witness to a murder.But Amelia intends to do more than simply be interrogated, much to the chagrin of Det. Ebenezer Gryce. She has questions of her own, and soon the police detective and amateur sleuth are in a race to see who can solve the crime first. “First published in 1897, this cleverly plotted mystery . . . featuring the first woman sleuth in a series, is a must for genre buffs.” —Publishers Weekly, starred review
