15d looks like NOCTURNE but you give the wrong number of letters and the letters you have seem wrong as well... or is this just me?

[pbeach]

Ahh that looks like the letters for 13d should go with 15d. Could you actually try and post the right clue, with the right number of letters and the right checked letters please.

13d beanfeast?

[Crocus1]

15d should be N?C?U??? - sorry!. So nocturne is correct. What would 'Impatient to get through improtant system' be? 5 letters
13d should be ?E?N?E??? - I managed to muddle them up!
Can you help please?
