1.

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

Why does Sirius Black have so many girlfriends? 

5.

Looks can be deceiving,
And they certainly were with me.

Betrayal and lying,
People dying,
Makes no difference to me.

I'd do anything to help him get that wretched boy.
That would make my master's empty heart fill up with bubbling joy.

Much in common I have with him,
We killed the people we "loved" or not.

I disguised myself for this man,
I'm doing everything I can.

For years and years I endured it all
Just to see that Potter's life come to a sudden halt.

Who Am I?
