Lion & Lamb

Rival Philadelphia private investigators Veena Lion and Cooper Lamb are two wrongs that can make a right. They are Lion & Lamb.
 
Eagles starting quarterback Archie Hughes is murdered. His even more famous wife, Grammy-winning singer Francine Hughes is suspect #1. 

For the defense: Cooper Lamb, private investigator to the stars. For the prosecution: Veena Lion, a sleuth so bright she’s got to wear shades.  
Between them, they know every secret in Philadelphia. Together, they carry the burden of proof.   
 
“Great storytelling…A spectacular murder case.” —Kirkus Reviews, starred review 

• “There’s an inherent satisfaction we get from murder mystery stories that feature entirely clever, yet diametrically opposed, but still wildly attracted to each other detective types. It scratches an itch. I should know—I’m somewhat of an expert. (On murder stories, not itches.)  Patterson once again takes us on a wild ride that keeps us turning pages to see if we’re all as smart as the characters in his story.”
  Nathan Fillion
• “A classic game of cat and mouse.”
