Confess to upsetting the maid at the end of the street (5)
I believe the answer is:
admit
'confess to' is the definition.
(I've seen this before)
'upsetting the maid at the end of the street' is the wordplay.
'upsetting' indicates anagramming the letters.
'at the end of' says to take the final letters.
The final letter of 'street' is 't'.
'maid' is an anagram of 'admi'.
'admi'+'t'='ADMIT'
(Other definitions for admit that I've seen before include "Stop being obstructive" , "Disclose" , "Accept" , "Take on" , "Allow access" .)
