Old witch's place in a good book
I believe the answer is:
endor
'a good book' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'old witch's place' is the wordplay.
I cannot really see how this works, but
'old' could be 'o' (common abbreviation eg in OE for Old English) and 'o' is found in the answer.
'place' could be 'end' (end is a kind of place) and 'end' is found within the answer.
A single letter 'r' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Another definition for endor that I've seen is " Witch of - - (OT)".)
