Volume’s dedication to its author? (4)
I believe the answer is:
Here is my best explanation:
'volume's' is the definition.
'dedication to its author?' is the subsidiary indication.
I cannot really understand how this works, but
'to' is present in the answer.
The remaining letters 'me' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
(Other definitions for tome that I've seen before include "Heavy volume", "dictionary?", "Weighty book", "Hefty volume", "Scholarly book", "Volume", "Large and scholarly book", "War and Peace, say", "Scholarly volume" and "Book".)
