Red Penguin Classics Pride and Prejudice, lost

I lost my red Penguin Classics edition of Pride and Prejudice yesterday around 3pm outside Waterstones on Northumberland Street in Newcastle. It's a standard paperback with a red cover, a slightly creased spine, and gold-foil lettering on the front. There’s a bright green ribbon bookmark sticking out from the top and a tiny coffee stain along the bottom edge that sets it apart. This book is sentimental to me because it was a gift from my grandmother, and I was in the middle of a reading slump when I last had it. If anyone found it, I’d really appreciate getting it back.
