Burgundy passport with biometric page

I lost my burgundy UK passport yesterday around 3pm near the Scott Monument on Princes Street in Edinburgh. It’s the standard adult passport with the royal crest on the cover and the biometric symbol inside. The cover has a small coffee ring stain along the bottom edge, and there’s a tiny crease on the top-right corner from a bag snag. I have a trip booked next week and a family event abroad later in the month, so I really need it back. If anyone found it, I’d be so grateful to arrange a safe return; I can collect from Waverley Station or meet in a central spot.
