The points of issue
First UK edition, Fourth Estate (an imprint of HarperCollins), London, 2006. This is the true first. A full number line ending in 1 on the copyright page is consistent with Fourth Estate house practice for a first printing, though the exact digits are not verbatim-confirmed from a primary scan; treat the number line as the printing indicator to check rather than as a quoted string. Confirm the Fourth Estate imprint and 2006 date against the later US Knopf printing.
Is this the true first?
UK Fourth Estate 2006 is the true first; the US Knopf is a later first-thus. Orange Prize winner and a key modern African-literature first.
Telling it from reprints & book-club editions
