George and Brooksie respond to a distraught woman who is worried that something bad has happened in a penthouse apartment. A drama of an eccentric and wealthy brother and sister emerges. The poor little rich kids are bored, and George discovers a collection of weapons, and a bizarre collection of native masks from Africa. What does it all mean?
When the brother falls to his death, the sister insists he died by being pushed out the window. George reviews the facts known about the crime, the police investigation, and the verdict of suicide. Is the suspicion of murder only in the sister’s head? When another body turns up as well, George puts on the pressure to force the killer out.
Brooksie uncovers the key clue to unravel the mystery, and the case is soon closed.
