Who is Rafe Sadler from the novel, Wolf Hall?

Rafe Sadler is Thomas Cromwell’s chief clerk and one of his most trusted allies. Indeed, Cromwell considers Rafe to be something of a son, and Cromwell approves of the fact that Rafe marries a pretty young peasant servant girl in his household named Helen out of love, rather than with an eye for personal gain or advancement. This encourages Cromwell to set up Rafe with his own household.
