Hi, Rusty!
I have just listened to Mark explaining "squid!
It sounds logical the way he puts it.........very well done in finding that!
He said his favourite clue was 19d: dentist.
Now strangely enough, I had seen that answer and parsing straight off this morning!
It is strange how differently minds can work over different clues......
I managed my one remaining unanswered clue...but it wasn't one of Mark's demonstrations.
However, I think I have it right?
25a: More wasted days by athlete half-heartedly covering kilometres (7)
drunker = more wasted (def)
d - days
run (n)er - athlete
k- kilometres.
I don't know why I couldn't see it earlier!
Thank you for your help and patience.
