Question about weird tale by English horror writer (8)

'horror writer' is the definition.
I know nothing about this answer so I can't judge whether this works.

'question about weird tale by english' is the wordplay.
'question' becomes 'why' (why is a question word).
'about' is an insertion indicator.
'weird' is an anagram indicator.
'by' means one lot of letters go next to another.
'english' becomes 'E' (abbreviation).
'tale'+'e'='talee'
'talee' is an anagram of 'eatle'.
'why' going around 'eatle' is 'WHEATLEY'.

Can you help me to learn more?
