The Risk Agent, by Ridley Pearson

This is a suspense novel set in Shanghai.   A private security firm, Rutherford Risk, works with a multinational doing business in China whose employee was kidnapped (along with an employee of the security firm).   The two heroes are Knox, a stereotypical action hero, and Chu, who has skills in forensic accounting as well as in spy craft; they both work for Rutherford.

This novel has enough plot movement to keep me interested to the end and reasonable character development.  Mr. Pearson signaled his intent to make this a series featuring the two main characters.   I'll probably read another one of these if I can borrow it from a free library or buy from Kindle at a deep discount.
