Inheritance Powder

you offered me a Valium
at least that's what I thought
I took it without question
(I like Valium a lot)
it seems you gave me thallium
a toxin most-renowned
this next part speaks of assets
with the last word being ground

Haiku Last Word Ground
the last word is ground
why is it italicized?
here it is not: ground

So where's the speak of assets
promised in the lines above?
I've once again led you astray
the last word being ground

Ground.
