The Mercer House, now called the Mercer-Williams House Museum, is located at 429 Bull Street and stands at the southwest end of Monterey Square, in Savannah, Georgia.
The house was the scene of the shooting death of Jim Williams' assistant, Danny Hansford, a story that is retold in the 1994 John Berendt novel
Midnight in the Garden of Good and Evil.
The house is currently owned by Dorothy Kingery, Williams' sister, and is open to the public for tours.
