Do all card players fall for her? (5,2,6)
I believe the answer is:
queen of hearts
'do all' is the definition.
The definition suggests a singular noun which matches the answer.
'card players fall for her?' is the wordplay.
I cannot quite see how this works, but
'card' could be 'queen' (queen is a kind of card) and 'queen' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for queen of hearts that I've seen before include "in a suit" , "Baker" .)
