HALLOWE'EN BAKE OFF

Here's a bit of sinister fun for Hallowe'en ...

TILL DEATH US DO PART

I cannot stand my ghastly wife:
instead, I love her sister, dear.
The former one pollutes my life.
The latter woman I revere.
I’ve hatched a plot to rid me of
my wife, I’ve simply had enough.

I’ve put rat-poison in a cake:
my wife is fond of sweets and treats.
One slice is all she’ll have to take:
rich cream will guarantee she eats
then she’ll be gone and I’ll have Maud.
It’s simple: just give fate a prod.

Maud’s phoned me to my work and said
she’s at our house to tend my wife
who’s got the sniffles, gone to bed: 
there’s germs around and flu is rife.
I fear I’ve made a great mistake:
Maud’s brewed some tea and scoffed the cake.
