A week on and it's odd how easily the unreal becomes the norm. Yesterday I was using the computer room in the Institute for Historical Research when an old man with a marshall armband entered the room. Apparently a suspect package had been found in Russell Square (now open, although traffic continues to be diverted) and the police were debating whether to carry out a controlled explosion.
Walking through the Square this morning I saw a big pile of flowers with various dedications to those who died. Judging by the dates on the notes they have been arriving all week.
