Take a look at the shared phrase between the two paragraphs.

[spoiler]lined up[/spoiler]

How could you apply this to the two clues?

Here is another tip:

[spoiler]Line up the books next to each other, Tails on the left, Heads on the right.[/spoiler]

Also:

[spoiler]Treat the numbers as letters.[/spoiler]

Have to say, my partner and I have tried this and still nothing has come to either of us, we must be over thinking it 🙁

This is one of those puzzles where you will see it clearly when you know it.

[spoiler]Think of another word for an enemy, perhaps in comic book terms; it is spelt out across the letters and numbers.[/spoiler]

I still don’t get it... how am I supposed to get numbers from letters?

I tried [spoiler]substituting based on the overlap between the two books, e.g. 1=E but then Y would be both 9 and 4... or is it based on the alphabet like A=1, B=2, but the numbers don’t seem to go until 26[/spoiler]

[spoiler]Place them side by side and you should read horizontally a synonym for nemesis[/spoiler]

I'm still confused... I think the answer is just what you said "[spoiler]nemesis[/spoiler]" and not any synonim, as it gave me the key for that... was I supposed to [spoiler]turn the heads edition (with the numbers) upside down so that 5->s and 1->i? I don't really get what indicated the way to pair them and which line to read?[/spoiler]
