'this irish novel' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'wow dim brits sat staggered' is the wordplay.
'staggered' indicates anagramming the letters.
'wow'+'dim'+'brits'+'sat'='wowdimbritssat'
'wowdimbritssat' is an anagram of 'AT SWIM-TWO-BIRDS'.

'by' acts as a link.
