The Fitzwilliam Museum
The painting is on the staircase and that is where Renee was sitting and painting. As she dropped the pad and charcoal, the former fluttered and landed three steps down while the latter tumbled down to the next landing. Renee herself held her head and backed away, oone step, two steps, falling backward and landing on her bum as she stepped to the landing above.
There was a painful jolt as she landed and as she did so, the sound of flies disappeared. There didn't seem to be anything damaged but clearly, there was SOMETHING in or around the painting, a malevolent presence of some kind, spirit perhaps? It was hard to know. Something to ask Father McGinty at her next confession assuming she ever went to confession again.
