Weekly Challenge (9/12 - 9/18) Bookworm ( alternative title' One lump or two?)

My love you’re a crime scene I’ve planned from afar,
You don’t know it yet ..but my darling ..you are.
Each morning you wake and lock the bathroom door,
and start humming tunes that I know you adore.
Perhaps you can visualise your day ahead,
the deals you will broker,
the lies you’ll have said.
What promises you‘ll make..
and whose heart  you will  break?
How clever you were with the lies you have told..
Pretending you love me but really so cold…
You put on a clean shirt, all starched and pristine,
You look like the charmer that you’ve always been.
You’re thinking of her now and how she will smell,
the way you seduced her and how you would tell
her tales of the sad life you’re spending with me,
and how loving her eases your misery.
She smiles at the thought that you think her divine.
She wonders and hopes that ‘one day he’ll be mine’
No.. no.. that won’t happen, because left to me,
I’m putting  some poison in his morning tea.
‘How bitter it tastes!’ will be your final word,
I’ll put in more sugar, and when I have stirred
I’ll sit back and watch as it slips down your throat,
my exterior calm, but inside I will gloat.
Your face changes from a self -satisfied smile,
to twisted, contorted ,demonically vile.
Your last second living I hope you will see,
that this  vengeance is sweet.. and your nemesis..  ME!
