Red Penguin Classics paperback with blue bookmark

I lost my red Penguin Classics paperback edition of Pride and Prejudice yesterday around 3pm near the Boots on High Street in Winchester, Hampshire. It's a well-worn book with a few creased corners and a bright blue ribbon bookmark poking out between chapters. There's a small coffee stain along the back cover and a tiny pencil note inside the first page that says 'Mom's gift' in my handwriting. This book means a lot to me because it was a gift from my grandmother, so I'd be really grateful to have it back.
