[Spoilers] Sir Harry Pearce

[Silktie]

I think, though, that the truth is in Harry's Diary version of events. He apparently had an opportunity to do something, but would have had a small chance of success at saving his friend. And also, any action taken by him would have blown their whole operation and specifically the asset they had in place - and who was in fact one of the men kidnapping his friend. So Harry, in essence, had to choose between maintaining their asset's cover and his friend's life.

The "Fight, goodie" line is the one that sways me towards this version. I just don't believe that Harry would be so flippant about her accusation if it were really true.
