I was sipping a takeaway coffee in the window of my new flat when a news alert popped up on my phone. Police were “increasingly concerned” for a missing woman’s welfare and were working “round the clock” to find her.The report said her phone signal was last picked up less than two miles from where I was sitting. It was March 6 2021, and I’d just picked up the keys to my new home in south London when the Metropolitan Police raised the alarm over Sarah Everard’s disappearance.Three days earlier, at around 9.30pm, the 33-year-old daughter, sister, friend and girlfriend, was walking home from a friend’s house when police officer Wayne Couzens arrested her under the pretence she’d breached Covid rules.
