Black leather Samsonite briefcase with brass clasp

I lost my black leather Samsonite briefcase yesterday around 3pm outside Waterstones on Western Road, near Churchill Square in Brighton. It's a medium-sized case, about 16 inches wide, with a brass turn-lock clasp and a small scuff along the lower right edge. The interior lining is a dark blue fabric with a faint red stitching along the seams, and there's a torn elastic strap from a missing USB charger tucked inside. It has sentimental value and I really need it back - it holds a notebook of project ideas and a photo that means a lot to me. If you found it, please get in touch - I'm hoping it's sitting safe somewhere nearby.
