But questions about the tragic event turn into whispers of murder, sending shock waves among members of the Dreghorn clan, who haven't seen each other in ten years. Now Rathbone must put his analytical and creative capacities to the test as he assumes the role of an amateur investigator. But while searching for clues and mulling over potential motives, he cannot help but wonder: Will another poor soul meet the same untimely end--and be silenced like the night?
