Profile
In June 1918, Derbyshire and her colleague Gerald Kneale investigated alleged hauntings (actually time shifts from ninety years in the future) at St Teilo's Hospital in Cardiff. They escorted Tommy Brockless out of his ward to ensure his cryogenic freezing and returned the "future" Tommy to his native time to ensure history would take its proper course. She died one year later at the age of twenty-six while in active service. (TV: To the Last Man) She worked alongside Jack Harkness. (COMIC: Rift War!)

She asked and received a favour from a British Army officer; she wanted to borrow a tank and travelled to 2008 to use it. (COMIC: Rift War!)

Following her death in 1919, Derbysire's body remained in cryogenic suspension in the morgue in the Hub, in Bay 15. (WEB: torchwood.org.uk) Whether her body was destroyed along with the rest of the Hub in 2009 is unknown. (TV: Children of Earth: Day One)
