Because a publisher's minion made a cock-up. There shouldn't have been any runners-up in there but someone, as I just found out, added an extraneous paragraph after final proofing.
Just to prove that Dave has not usurped my identity:
In the context of "final proofing" what about:
p.17 The Earl of Plymouth was not royalty
p.20 "...the club badge comprised of" should be either "comprised" or "consisted of"
p.42 "fire" should be "fired"
p.48 "once" should be "one"
p.54/55 Why is Young labelled in the diagram while Agbonlahor is mentioned in the text?
p.65 "First World War" should be "Second World War"
p.86 Forced line-break near bottom before "fragile"
p.123 Mis-spelling "Freidal"
It's still a jolly good book and a bargain at the price.
