Snipers

The Carnival Sniper-as famous as Jack The Ripper. And like Jack The Ripper, never caught, his identity lost to history. In 1913, the Carnival Sniper terrorized Vienna, murdering the famous and not-so-famous alike. Police Detective Johann Runge never caught the Sniper and his failure defined the rest of his life. In 2005, bestselling crime writer Sofie Branstadter receives permission to use modern forensic investigative techniques on the Sniper's victims.
She believes she can figure out the identity of the Sniper, but she needs the help of Runge's great-grandson, classical pianist Anton Runge. Together the two of them plunge into a world of scientific evidence and fantastic clues, all leading to one unbelievable conclusion.
