After Strangways and Mary Trueblood are killed in the opening chapter of Dr. No, their bodies are deposited in a body of water outside Kingston.
As the first flames showed in the upper windows of the bungalow, the hearse moved quietly from the sidewalk and went on its way up towards the Mona Reservoir. There, the weighted coffin would slip down into its fifty-fathom grace and, in just forty-five minutes, the personnel and records of the Caribbean station of the Secret Service would have been utterly destroyed.
The Mona Reservoir is the main water supply for Kingston, located in the neighborhood of Mona, about eight kilometers outside of Kingston.
After many years of development and several setbacks, the Mona Reservoir went into service in 1959.
