Riddle 2

First think of the person who lives in disguise,
who deals in secrets and tells naught but lies.
Next tell me what's always the last thing to mend,
the middle of the middle and end of the end?
Finally give me the sound often heard
during the search for a hard-to-find word.
Now string them together, and answer me this,
what creature would you be unwilling to kiss?
