Castor Oil Plant

...you shall be banned from the soil that opened its mouth
to receive your brother's blood from your hand.

Castor oil plants are universal
As sin. In late 1978,
Social enemy Georgi Markov fell
To an umbrella’s tip in a London street,
Object of brotherly hate once more rehearsed,
Resurrecting Abel’s cry from the earth.
One man has taken aim again, and cursed
In act he roots his will to homicide –
Losing heaven’s harvest, he gains the world’s dirt.
Plenty of nothing stains the working hands
Leaving a cavity in a crushed heart.
Again, man the engineer looks but finds
Nothing to plan man's rest or hide the blood
That signed Cain's contract - ink that never dried.
