An inkling

I do not have full proof
That the plot was hatched under his roof;
But I was given an inkling
Of how the boat started sinking;
I was told where he was at the time;
And how he did not care a dime
When the news was narrated to him;
Instead, he said it sounded like a film;
And pushed me to an unholy conclusion;
And what I took as a final decision.
