I've filled my grid but several i the bottom right have me puzzled. I've either guessed some wrong or the explanations are just eluding me.
For 15d Killer of 25 sins (8) I have ASSASSIN.
For 25ac Sweve prejudice (4) I have BIAS. This doesn't really fit with 15d though if it's an anagram of SINS and 25ac.
Is ASSASSINS wrong? Is the killer a person/proper noun?
17ac Arts where some say they're taught (6)
I have SKULES but I'm somewhat doubtful about this.
