Rachel Hennessy was the daughter of J. Tucker Hennessy. After her father was killed by a brother, their home was sold to future Governor Smart. Rachel, aware of these facts feared that the Governor might have her killed over the shady deal. Rachel was killed in a car accident two years before her brother attempted to kill Governor Smart, but not before she left a letter with these facts in a jewelry box that Dick Tracy would find. Rachel haunted the Hennessy mansion before it was destroyed, asking Detective Tracy to help get “Justice done”.
