Sally Lee is the name of one of the two lead female characters in the stage play Fiddlers Five. When the play was reworked into Fiddlers Three the character was given the name Sally Blunt and became the only female lead role. Christie envisaged the part to be played by Margaret Lockwood. Sally is the loyal and streetwise secretary of Sam Fletcher. She masterminds the "fiddling" required to help the conspirators secure their badly needed money.
