[spoilers] Harry and Ruth

[Tea Lady]

Yes that's right. As well as the obvious episode of Harry having his safe broken into, he also took work home in 7.7 when he took that dossier home. I think he let Ruth get away with it in part because he felt sorry for her because she was lonely like he was. She wasnt really doing any real harm. The ending though was a little confused as Ruth didnt seem at all surprised that Harry knew what she had been up to.
