Difficult enough but a reasonable workout from Brendan. I'm not seeing the parsing of the writing part in 13a. I also think the definition is a bit loose in 10a. If anything the answer means the opposite no?
FOI 10a. LOI 5d. COD 18a because the parsing made me laugh.
Thanks to Brendan. Not sure about next week as I solved it already over the bank holiday before they took it down.
