[spoilers] Sir Harry Pearce 2.0

[Silktie]

I thought Harry's reaction towards Zoe and Danny came from his own ambivalence about what Tom was up to. He knew that if Tom was actually innocent, the accusations of Zoe and Danny would harm not only Tom's career, but also those of the younger two, and would destroy the working relationship between Tom and them. Harry, at this stage, is still giving Tom the benefit of the doubt, which I think is proper, as Tom has always been loyal up till then. He knows Tom is becoming emotionally unstable and is worrying what direction this will take, but probably wants more proof that Tom is actually busy with something that presents a danger to the country. However, when Ruth tells him that the hit-man is already dead, this to Harry is final proof that Tom is playing them all for fools and is betraying them. He then becomes decisive in his actions against Tom.
