AN EMBUGGERANCE

Folks,

I would have liked to keep this one quiet for a little while, but because of upcoming conventions and of course the need to keep my publishers informed, it seems to me unfair to withhold the news.  I have been diagnosed with a very rare form of early
onset Alzheimer’s, which lay behind this year’s phantom “stroke”.

We are taking it fairly philosophically down here and possibly with a mild optimism.  For now work is continuing on the completion of Nation and the basic notes are already being laid down for Unseen Academicals. All other things being equal, I
expect to meet most current and, as far as possible, future commitments but will discuss things with the various organisers.  Frankly, I would prefer it if people kept things cheerful, because I think there’s time for at least a few more books yet :o)

PS  I would just like to draw attention to everyone reading the above that this should
be interpreted as ‘I am not dead’.  I will, of course, be dead at some future point, as
will everybody else.  For me, this maybe further off than you think – it’s too soon to tell.
I know it’s a very human thing to say “Is there anything I can do”, but in this case I
would only entertain offers from very high-end experts in brain chemistry.
