5 maybe through

23d aboral
17d flagella
I guess you have strident for 4a? I'm finding it difficult (as you are) to find a satisfactory answer for 5d!! What do you have for 8d?

[imac]

5d thrutch

i think 5d may be through, is there a chance you have one clue wrong

[dauv]

Fabgrandad - I think 13a is Peterhead so through cannot be right
