DCI Mason is doing the rounds in the Square. The first person to be interrogated is Grant, who tells him they were "just bickering" when Tiffany tripped and fell. Bianca has no trouble in telling Mason what she things of Grant; she tells him he'd hit Tiffany last Christmas and that this time Tiffany had found out Grant was having an affair. When Mason questions Peggy she begrudgingly tells him she saw nothing, but that Jamie may have done!
