Who killed Dr. Harvey Burdell?

Though
there are no witnesses and no clues, fingers point to Emma Cunningham,
the refined, pale-skinned widow who managed Burdell's house and his
servants. Rumored to be a black-hearted gold digger with designs on the
doctor's name and fortune, Emma is immediately put under house arrest
during a murder investigation. A swift conviction is sure to catapult
flamboyant district attorney Abraham Oakey Hall into the mayor's seat.
But one formidable obstacle stands in his way: the defense attorney
Henry Clinton. Committed to justice and the law, Clinton will aid the
vulnerable widow in her desperate fight to save herself from the
gallows.

Set in 1857 New York, this gripping mystery is also a
richly detailed excavation of a lost age. Horan vividly re-creates a
tumultuous era characterized by a sensationalist press, aggressive new
wealth, a booming real-estate market, corruption, racial conflict,
economic inequality between men and women, and the erosion of the old
codes of behavior. A tale of murder, sex, greed, and politics, this
spellbinding narrative transports readers to a time that eerily echoes
our own.
