Three clues holding me up - sorry I can't give anyt letters but the answers clash in some cells and I want to be sure I put the right letters in.
3d : Plunder stashed up in enclosure in Perth provided new kit (8)
7d : Second-rate, old, dissolute wretch shows no modesty - it's a harrowing thing (5)
26d : An honour? I'm surprised - but that's my charm (5)
Any help is greatly appreciated, and explanations if possible. Thanks in advance.
