Lucy Wilson is the granddaughter of the iconic Doctor Who favourite Brigadier Alistair Lethbridge-Stewart. Recently in the series, Lucy had one of her biggest adventures yet in the Mystery of Lucy Wilson trilogy, where she time travelled back to 1985 Melbourne to meet plant people from outer space (Memories of the Future), followed by killer koala bears (Rampage of the Drop Bears). She was then thrust forward to encounter giant spiders in an alternate 2020 apocalyptic Earth (Apocalypse Tomorrow). As if this wasn’t enough, Lucy also visited her first alien planet in The Web of Terror.
This time, however, Lucy is spending time away with her best friend Hobo at her brother’s house in London. After a whirlwind of adventures over the past few months, the duo are under strict orders not to go exploring London on their own. But Lucy’s time ring has other ideas. Soon they’re cast back in time to London to World War II during the blitz.
