Amid commotion, doctor slayed sloth? (6,3)
I believe the answer is:
deadly sin
'amid commotion doctor slayed sloth?' is the definition.
I know that 'sloth' relates to this answer.
'slayed sloth?' is the wordplay.
'slayed' becomes 'deadly' (I can't justify this - if you can you should give a lot more credence to this answer).
'sloth?' becomes 'sin' (sloth is a kind of sin).
'deadly'+'sin'='DEADLY SIN'
Can you help me to learn more?
(Other definitions for deadly sin that I've seen before include "greed, or lust" , "Lethal lapse like pride, gluttony or envy" , "It's one of seven, gluttony say" , "Eg, lust or gluttony" , "Eg, lust or pride" .)
