Panic Room

High on a Cornish cliff sits a vast uninhabited mansion. Uninhabited except for Blake, a young woman of mysterious background, currently acting as housesitter. Cunningly concealed, steel lined, impregnable and apparently closed from within. She's too busy being on the run from life, from a story she thinks she's escaped. But her remote existence is going to be threatened when people come looking for the house's owner, rogue pharma entrepreneur, Jack Harkness. Soon people with questionable motives will be asking Blake the sort of questions she can't or won't want to answer.
