I've managed to do a few more, but I'm still not sure if they are correct. Would prefer an explanation as to how you arrived at the answer, if my answers are incorrect thanks. Here goes......
A) Rich, finding husband's absence an asset (4)
Is it PLUS? Plush = rich, minus the h (husband).
B) King Edward's voice worn out? (6)
Is it TATTIE?. I don't understand the voice worn out part of the clue.
C) Tom Ellis's lead part in Macbeth (6)
Is it HECATE? Doubt it? TE for lead initials of Tom Ellis, but how does heca relate to part?
D) Poor Voltaire - Cesario's gone to soak (3)
Haven't the foggiest.
E) Hit unconvincingly but get boundary (4)
Is it FOUR? I don't think so . Maybe EDGE? Explanations as per usual please.
