Anna (Arachnids in the UK)

From Tardis Wiki, the free Doctor Who reference

Anna was a member of the admin team at Sheffield Hallam University studying arachnids and arthropods, especially spiders.

She lived in Flat 27 in the Park Hill estate. She was the neighbour two doors down of Hakim, Najia, Yasmin and Sonya Khan.

She was killed by a giant spider which grew to an enourmous size due to toxic waste. Her colleague Dr Jade McIntyre grew concerned for her, and searched Anna's apartment alongside the Thirteenth Doctor and Ryan Sinclair, where they discovered Anna's corpse. (TV: Arachnids in the UK)
