Can't get my head around my last two.
10ac Personal item found by whispering burglars (8)
?N?C?E?S
SNICKERS or KNICKERS perhaps? I can see nickers for burglars but not the whispering.
21dn The novel with very uplifting character (5)
E?H?S
ETHOS maybe but I can't see why.
Any help from brains better than mine today would be much appreciated.
