Cricketer cutting fish to detect fishiness (5,1,3)
I believe the answer is:
smell a rat
'cricketer cutting fish' is the definition.
I know nothing about this answer so I can't tell whether this works.
'detect fishiness' is the wordplay.
I cannot quite understand how this works, but
'detect' could be 'smell' (I've seen this in another clue) and 'smell' is located in the answer.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for smell a rat that I've seen before include "Find something fishy" , "Detect something suspicious" , "Suspect trickery (colloq.)" , "Suspect deception" , "Have suspicion something is afoot" .)
