*The Trade*

This book is about what I call the Trade, the growing international business of political kidnappings, according to the US Treasury the most lucrative source of income, outside of state sponsorship, for illegal groups. But it’s more than about money. It is about my attempt, yes, to find the answer to two questions which have haunted me for nine years: Who kidnapped me, and why?

That is from Jere Van Dyk, The Trade: My Journey into the Labyrinth of Political Kidnapping.

Solve for the equilibrium, as they say.  The puzzle, of course, is why there are not more kidnappings for revenue.
