SAM DURELL once said his job was troubleshooting for a government agency so secret that even the government didn't know about it.

This time everybody seemed to know more about his job than he did.

This time he was practically dead before he started…a prisoner buried alive in a dark, suffocating cell in the sewers of Bangkok.

No one was supposed to know he was even in the city. Yet only minutes after his arrival he'd been ambushed and kidnapped.

Someone had known. Someone had seen him. Someone had been waiting for him.
Who? How?

Sam decided to worry about that later.

First he had to get some fresh air.
