For me - in one of the Chalet school books, Joey (as an adult) is once seen with a huge sheaf of galley proofs, and I think I got the impression they were long and thin. What are galley proofs? Are they different from ordinary proofs? (and yes yes, I could just google it but it has bugged me for a long time so I feel the need to unburden myself).
Secondly, in The Dark is Rising, Will puts the sign of Iron onto his belt. Now how does he get his belt through the sign of the circle quartered by a cross in such a way that it later burns a pattern of a circle quartered by a cross onto his skin? Wouldn't the belt cover bits of it?
Years, this has bothered me. Years.
