John Corey is my second favorite cop. Especially his wit. "The Lion" is Mr. DeMille's follow up to "The Lion's Game" and is very violent.
A straightforward story that doesn't thrill and not much mystery. I much prefer these novels when there are conspiracies involved.
I am afraid to say Mr. DeMille's best work may be behind him. If you want good mystery/thrillers by Mr. DeMille read -
"The Charm School"
"The General's Daughter"
