First edition, first impression, signed by the author on the dedication page. First published on 8 July 2000 by Bloomsbury in the UK and Scholastic in the US, the fourth novel in the series was the first to receive significant media attention, and a release at midnight. The advertising campaign would be known as "denial marketing" by the publishers (Errington, p. 252).
This copy was signed by the author at Harrods on 17 July 2000 and includes the "golden ticket" for the event loosely inserted.
Octavo. Original pictorial boards. Together with Harrods ticket loosely inserted. With dust jacket.
Some negligible marks to edges: a near-fine copy.
Errington A9(a).
