In the early 1960s, a US Marine Colonel and his wife were stationed in Haiti.
On their return to the States in 1963 they wrote a book that criticized the regime of Papa Doc Duvalier.
A Haitian newspaper published an article saying that the Colonel and his wife had been ritually cursed by Voodoo priests.
The first draft of the book was lost in the post to the publisher.
The second went to the wrong address.
The third could not be typed, the typewriter blocked.
Then the Colonel broke his leg. A journalist who was meant to interview him about the book was rushed to the hospital with grave appendicitis and could not make the appointment.
The Colonel was then attacked by a rabid dog.
Even so, the Colonel and his wife planned a holiday to Haiti.
He died from an unexpected heart attack before being able to travel.
The Voodoo curse had achieved its object.
But what is the Voodoo? And why is it limited to Haiti?
