Just in from Robert and Sally
"Robert is resting, it appears that he will have to take a course of mecication, but with that and rest, he should recover no problem from his ailment"
"He will need a couple of weeks rest, but at this stage, we are not cancelling our Worldcon trip, and we hope that he will be recovered for this relaxing weekend."
"I am just very sorry if I have let down any fans. The signings and the meeting of my readers is very important to me, and I have never had to cancel a signing before. I am very sorry"
"Many thanks for all the well wishes, your messages online cheer me no end, many thanks for your understanding, and I hope to see you all soon"
