Black leather briefcase with red interior

Lost my black Samsonite briefcase yesterday around 3pm. I was at the Farmington Library on Main Street, then grabbed a coffee at Brookstone Café in the same block. The case is medium-sized, black leather with a brass latch and a red interior; it has a small dent on the bottom-right corner and a blue leather tag embossed with my initials PP. Inside are client documents and a USB drive with drafts—it's really important I get it back.
