Pair took in wad, anxious to secure folio (3,2,1,4)
I believe the answer is:
two of a kind
'wad anxious to secure folio' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'pair took in' is the wordplay.
I cannot really see how this works, but
'pair' could be 'two' (I've seen this before) and 'two' is present in the answer.
'in' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for two of a kind that I've seen before include "less than flush" , "Twins" , "Like characters in 5D [WAITING FOR GODOT]" .)
