"When Teddy Fay receives a freelance assignment from a gentleman he can't refuse, he jets off to Paris on the hunt for a treasonous criminal. But as Teddy unearths more information that just doesn't seem to connect, his straightforward mission becomes far bigger--and stranger--than he could imagine. The trail of breadcrumbs leads to secrets hidden within secrets, evildoers trading in money and power and a global threat on an unprecedented scale. Under the beautiful veneer of the City of Lights, true villainy lurks in the shadows...and Teddy Fay alone can prevent the impending disaster." -- jacket.
