13 (ad)verse

[Mamyalynne]

13 Vi(r)gil

[Neveracrossword]

13 . Averse would be reluctant, drop the 'a' (miss opening). Verse, poet's work.

[Mamyalynne]

ignore my 13

[Toorak]

(A)verse is better...

[dannyk13]

r(Regina-queen) inside spare(extra)m+ d(diamonds)
c(caught) inside anagram of treason +s(son)
(a)verse
Ep(old record) + I(writer) + tome(book)
Staunch (double meaning)

[jenniferd]

Thank-you. Still querying 19d as a bad clue. Can see "DID BOX" = Sparred. Not too clear about further breakdowns. Where does the M come from dannyk or did you mean "spare (extra) r + d (diamonds)

[dannyk13]

Jennifer, ignore the 'm' I didn't notice it.

[jenniferd]

OK. Thanks dannyk. Will do.

[Mamyalynne]

19 Sparred - did box

Spare D round R(Regina)

//Wrong clue for 19down//
Clue is correct. Clue number is wrong.
