Question about weird tale by English horror writer (8)

'horror writer' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'question about weird tale by english' is the wordplay.
'question' becomes 'why' (why is a question word).
'about' means one lot of letters goes inside another.
'weird' indicates an anagram.
'by' is a charade indicator (letters next to each other).
'english' becomes 'E' (abbreviation).
'tale'+'e'='talee'
'talee' anagrammed gives 'eatle'.
'why' placed around 'eatle' is 'WHEATLEY'.

Can you help me to learn more?
