Neptune lifted the tarp and hunkered by the body for a moment, looking the man over. Near the body was a pair of glasses, its lenses broken, the arms open." He pulled the tarp back over and stood up. "This was murder, not suicide." With those words, Neptune opens a can of worms. What the police thought were suicides - men jumping from upper story windows in absolute terror, trying to escape their demons, needed a second look. Neptune and Shark are hired by Belinda Hyde to investigate the death of her brother, Stephen. She doesn't believe it was suicide and wants them to prove otherwise. Collaborating with Sergeant Wolf of Scotland Yard they start to see similarities between Wolf's suicide investigation and theirs. In both cases there is an unknown mysterious woman involved. Neptune suspects she is behind the deaths. Determining her identity and locating her is relatively simple for the private detectives, proving her guilt though presents a quandary. They know she's guilty, they just can't prove it and when potential witnesses start dying, they realize she is cleaning up after herself and destroying her back trail so rapidly that she's always one step ahead. Can they stop her before more men die? They'll do their damnedest.
