Crossword Genius

Popular book he can persuade almost anybody to buy (4,6)

Ross

I believe the answer is:

best seller

I'm a little stuck... Click here to teach me more about this clue!

'popular book' is the definition.
(I've seen this before)

'he can persuade almost anybody to buy' is the wordplay.
I cannot quite see how this works, but
'persuade' could be 'sell' (selling is a kind of persuading) and 'sell' is found within the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for best seller that I've seen before include "Book bought by many" , "Blockbuster" , "Popular book" , "Book bought in large numbers" , "What many people are buying" .)

I've seen this clue in the Evening Standard.
