Identification

How to identify this edition

Sphere announced the fifth Cormoran Strike novel for 29 September 2020 and published it in London on 15 September 2020. The first British printing is a hardback of 944 pages in black boards with gilt decoration and lettering on the spine and front, in a jacket by Duncan Spilling priced £20.00. The first impression has the full number line 1 3 5 7 9 10 8 6 4 2 on the copyright page; later impressions drop the low numbers, and a fourth printing begins at 5. Two dealers offer copies signed as Robert Galbraith with a hologram sticker and say about fifty were made; treat that figure as their claim.
