21d was my FOI contrary to others solvers who had it as their LOI -funny how minds work. Mind you I start in the SE as sometime told me the setters had run out of steam by the time they get there.
LOI was 22 which took me 15 mins of going through the alphabet with the second and fourth letters in place.
Can't say I ever referred to them as the answer.
Two completed in a row. Can I make it a hattrick next week?
