Incase you don't know, the characters are (taken from the file names) PC Dibbins and Edwina. It looks like Edwina is watching her TV and is worried, angered (or both!) about something she is watching. She is also surrounded by plants and is scrumpling some paper in her hand.
Time to speculate on how we think these characters fit in!
