I'm stuck on the last two clues which are 4(a) "A small prayer against one being recorded in manuscript" (6) I have ?A?T?S and think it can be spelt mantes or mantis, also 20(a) "New stationer having reorganised first is booming" (10). I have ?T?N?O?I?N and think it's stentorian? Please confirm and explain both. TIA
