Gertrude Nox Wolfe (b. 18 August 1980) was the daughter of the famed Paranormal Detective, magi-philosopher and Squib, Edward Balthazar McRosen (nicknamed by the British tabloids "Mad Rozza") and his Muggle ex-wife, Agnes Wolfe. Nox was in the process of completing her detective training when the war broke out during 1997-98. Though unbeknownst to her, the war deeply affected her life. With the mysterious disappearance of her father, Nox inherited both Edward's Paranormal Detective agency and hefty debts.
