Leaseholder puts number on a book (6)

I believe the answer is:

tenant

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

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

'number on a book' is the wordplay.
'number on' becomes 'ten' (ten is a kind of whole number. I am not sure about the 'on' bit.).
'book' becomes 'NT' (New Testament).
'ten'+'a'+'nt'='TENANT'

'puts' is the link.

Can you help me to learn more?

(Other definitions for tenant that I've seen before include "his flat?" , "he or she rents" , "Person renting property" , "Property renter" , "Anne Bronte's novel 'The ...... of Wildfell Hall'" .)

I've seen this clue in The Mirror.
