SPOILER ALERT!
Getting Hooked Everytime

I just discovered Douglas Lincoln and Preston Child last year and I first read their book Dance of Death which features my now-favorite detective, Special Agent Aloysius Pendergast.
Now I'm on their #9 Pendergast series because I feel the need to follow my favorite agent's adventures. He is quirky and unusual. He's the type of guy I would have wanted to meet in real life.
As of this current book I'm reading, I'm currently disappointed because Smithback's dead. He's one of my favorites also. He's a journalist and a friend of Pendergast. His unexplained death moves Pendergast and another associate, D'Agosta, to look for his killer.
What gets me hooked?
It's the entirety of it all.
