'perspiring right behind' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'the quarry?' is the wordplay.
I cannot really see how this works, but
an anagram of 'the' is 'het' which is located in the answer.
This explanation may well be incorrect...
