Nancy has long brown hair and bright green eyes. She is intelligent, cunning and cautious, and committed to the cause, diligently and pragmatically investigating cases in London. She has quite a few favors and connections, and uses them at times to get herself out of trouble. She is ruthless and not quite tolerant of criminals, however she is patient, calm and rational. She is not a stellar fighter but she tries her best. She does have a history of personal affairs though.
