Cream duvet cover with navy piping

Yesterday around 3pm I was changing sheets in my friend's apartment near the Hotel Monaco on Light Street in Baltimore when my cream Brooklinen duvet cover, queen size with navy piping, disappeared from the bed. It's a Brooklinen Luxe duvet cover in cream, with a navy piping edge, a zipper closure, and a tiny monogram 'PK' in navy thread on the inside corner; there’s a faint coffee stain along the bottom edge from last week. This duvet has sentimental value for me—it's part of a set my grandmother gave me, and I really need it back. If someone found it, please email me at [email protected] so I can arrange details for pickup.
