I found this puzzle a slightly strange one, in that I had pretty much all the endgame sorted with only a third of the clues solved.

The five perimeter clues were generous in their wordplay, resulting in five synonyms for the word ‘friend’:
- ASSOCIATE
- CATER-COUSIN
- BELAMY
- COMRADE, and
- MATE
The spacing given in Ring 3 was very helpful, where I think I had .OGAN fairly early on as the character’s surname, and a message that looked much like BLESS ME FATHER FOR I HAVE SINNED. A quick bit of help from Google and this gave me MAEVE BINCHY for the central Author and BENNY HOGAN the Character. I liked the longer version of the quote, which was hiding a letter at a time in the Clues and which, according to quotes.net, reads:
Bernadette ‘Benny’ Hogan:
Have… have you ever gone all the way with a girl?
Jack Foley:
No. Not quite.
Bernadette ‘Benny’ Hogan:
Would you like to?
Jack Foley:
Now?
Bernadette ‘Benny’ Hogan:
No. It wasn’t an invitation – just a request for information.
Having got these thematic bits sorted this early (to be honest it took until near the end to confirm where the last pair of consonants from the Author’s name fitted in the asterisked cells), it still took until late Friday evening to polish it off!
And the Title? Are we to read that as Disc O’ Lovers? That’d seem a reasonable interpretation given the Dublin setting. Maybe?
Cheers all,
