there is no other info on 17 down . 9 letters , first is d a straight line and r is last letter
ROSEBUD often sets clue in this manner.
for instance 23 d . reads D ,a down arrow line to final letter R.
the answer is actually RAISED
so possibly the ans. to 17d. is meant to be reversed too i.e. r first letter and d the last
a regression.
i could not get BRRR.
NOW I HAVE IT.
