We didn't actually see anything beyond Robert sliding the door shut, but assume the worst. Rob, Paul, Izzy went to the office when the business bloke failed to show up for a meeting, and Rob noticed a bloodspot on the desk. Wiped it up sneakily without anyone seeing, though, so everyone, including the Police, think that the businessman is just 'playing away'. He's a bad'un, that Robert. He'll come to no good, you mark my words................................
