The Girl Upstairs: An absolutely gripping psychological thriller debut with a jaw-dropping twist from a stunning new voice in crime fiction in 2025

*Don’t miss The Lost Wife – the brand new jaw-dropping thriller from Georgina Lees* ‘Compelling, heartbreaking and beautifully written. This superb thriller will stay in my mind for a very long time’ B P Walter, Sunday Times-bestselling author of The Dinner Guest How well do you know your neighbour? Would you trust them with your life? I heard Emily before I saw her. The harsh smack of heels against cheap wooden floorboards. The loud phone calls. The incessant music. I knew Emily before I met her. Discarded receipts in our communal hallway. Sticky leftovers in the shared food waste bin. Wine shop vouchers in the letterbox. Now she’s gone missing, and I’m the only one who can find her. The only one who can save her. Because I know her best, and I heard everything. The Girl Upstairs is a spine-tingling psychological thriller of grief and obsession that explores how lonely London can be and how sometimes it’s our neighbours who see us most, who know us best… A must-read for fans of Lisa Jewell and Sarah Pinborough.
