Von Tunzelmann, an Oxford-educated historian, has also tried but failed to interview "Baby Doc" Duvalier. A series of political convulsions - attempted assassinations, bomb plots - has followed the despot's expulsion from the Caribbean in 1986 and no doubt he sees journalists and even historians like von Tunzelmann as part of a larger threat. Red Heat, a zingy, well-researched history of the Cold War and its depredations in the Caribbean, offers a James Ellroy-like canvas of Duvalierist corruption, dubious CIA operatives and White House paranoia.
