Whisper was born on 'Lung Block', on Seventh Avenue, at 142nd Street, where death from TB was twice as high as anywhere in New York. During his childhood, Whisper's quiet voice is attributed to a bout of tuberculosis during infancy, from which one and a half of his lungs had to be removed, leaving him with only half a lung with which to breathe and talk.
Later, Whisper became an assistant to Whisper the negro gang in Harlem run by Mr. Big working as a telephone messenger. When James Bond escapes Mr. Big's men, he is sent out to pursue him, though unsuccessful. He is arrested in the end of the novel after Mr. Big's death.
