Met Rolf a few years ago at a craft fair. He and I commiserated as "craft widows", and loitered around the coffee bar, keeping an eye on the ever-growing piles of Stuff that our dearly-beloveds were purchasing. He was polite and friendly, but nothing like his screen persona (which is reasonable, since he was on a day out with his wife, not being an entertainer).
When rumours of his arrest began to circulate I was appalled - more so than with any of the other arrestees. This is probably because he was such a big (and innocent) part of my childhood. I very much hope that he has been arrested for what he might know about others, rather than as a consequence of allegations made about him directly.
