Frank Malloy's latest client is the well-dressed Will Bert. He's searching for his brother, a newsboy named Freddie, so he can share his new financial good fortune. Frank makes quick work of the case and locates Freddie, but a happy reunion between brothers is not in the cards.

When Will's name is mentioned, Freddie runs off--only to be found dead a short time later. Suspicious, Frank tracks down Will who spins a tale of lust and deceit involving a young society woman, Estelle Longacre, also recently deceased. Frank can't be sure if Estelle's risky behavior and the company she kept was to blame, or if her own ruthless family had a hand in her death.

Frank will need Sarah's help to unearth the dark secrets of the wealthy Longacres and to discover if there is a connection between Estelle and Freddie's death. Together they must navigate a perilous underground web of treachery to find the truth.
