Risky act by man, a little dazed after ecstasy and a beer in escapade (4,2,3,4)
I believe the answer is:
leap in the dark
'risky act by man a little dazed after ecstasy' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'a beer in escapade' is the wordplay.
I cannot really see how this works, but
'beer' could be 'dark' (dark beer is a kind of beer) and 'dark' is found within the answer.
'in' is within the answer.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for leap in the dark that I've seen before include "Guess" , "new adventure" , "attempt to fly by night" , "Daring step with unpredictable results" , "Jump into unknown" .)
