Being underconfident, I would appreciate confirmation of my solutions to the following clues:-
6A 'Biting a Spanish hero' (4) = A CID (El Cid)
7D 'Old French ready mixed cement traps one' (7) = CONFINE (CONcrete, old F rench, I) ??
25A 'Get used to Rail Union that is out' (5) = INURE (NUR IE)
20D 'Detective's given name of woman clue unravelled' (7) = HIRSUTE (??)
