Agreement to read pamphlet (8)
I believe the answer is:
contract
'agreement' is the definition.
(I know that agreement is a type of agreement)
'read pamphlet' is the wordplay.
'read' becomes 'con' (I've seen this in other clues).
'pamphlet' becomes 'tract' (synonyms).
'con'+'tract'='CONTRACT'
'to' is the link.
(Other definitions for contract that I've seen before include "Covenant" , "Come down with" , "Agree - get smaller" , "Shorten" , "Shrink in legal agreement?" .)
