A New York corporate lawyer falls eighteen stories from the Black Eagle Building. Suicide, cops say. That Hollings Harland was part of a black organization, cornering the market on copper, and about to be exposed to the world. He had just excused himself from an acrimonious meeting with the wealthy Johnston Barker, perhaps another agent of the organization. Could Harland have defected? Spunky part-time snoop Molly Morgenthau Babbits thinks something fishy is going on. She's opening her own informal investigation into the facts with the help of a connection on the Black Eagle's staff and suspects the worst: murder most foul!
