Undercover - going underground

This blog has been up and running for more than 48 hours now, but we are having to announce a brief departure. We'll both be away for the next fortnight, and for legal reasons we won't be able to leave the comment thread open, which is a bit annoying but we will be back. The good news is this experiment seems to be working. We've had useful comments so far — particular thanks to contributors TheseAreEmptyTimes , haukurmar , maggieTee , spiedon and CHARPER . Thanks also to those of you who have emailed Paul or Rob (or both). We totally accept that a lot of sensitive information can't be posted on this blog — and we discourage anyone from doing that. We've received some great leads via email that we're already working on (you know who you are). See you in a fortnight.
