Tonight’s BSFA meeting features Chaz Brenchley, interviewed by Iain Emsley.
The meeting takes place in the upstairs room of the Star Tavern in Belgravia; there’s a map here. EDIT: the interview starts at 7, but there are usually people around from shortly after 5.
BSFA members and non-members alike are welcome, and there’s no entry charge (but there is a book raffle).

…and it’s worth saying that the interview will probably start around 7pm but that fannish types are likely to be there from 5 or 6.
Details, details …
Oh, arse, is that tonight? I was thinking it was next week. I won’t be able to make it, then.
