Pernicious
ghastly Gordian quandary to elucidate
Pestiferous
nebulous necrotic novelty to navigate
Labyrinthine
contumely carnal [bad word] to cogitate
Serpentine
An exulcerated entanglement to execrate

Hands stained and filthy from digging deep for the answer
That lies at the heart of the matter of splatter

Eschatological
The grave matters with which we [bad word] Pathological
The perverse perpetuation of this [bad word] puzzle
Repugnant
The wretched riddle unravels in a reeking revelation
Repulsive
The final fetid farce yields such a rancid realization

Now your morbid curiosity may finally be answered
Deep in the heart of the matter of splatter

morbid matter on which to meditate or mutilate
deathly detail to deliberate and desiccate
sombre study in which sagacity is tantamount to insanity
An insalubrious interest in the inhumed and the unsanitary

An unhealthy pursuit of the [bad word] and parturient
feculent fixation upon the fetid filth and excrement
An exhaustive examination of the excreted and the exhumed
tireless appetite to hill the silt atop the tomb

Nebulous
The sanguineous solution is seldom seen before the last
Amorphous
Seemingly always six deep feet beyond your grasp
Funereal
Carnal cartography to chart the course of life's denouement
Corporeal
The wretched revelation that you sought proves harder to swallow 
than you'd thought

That anatomy is destiny is the unforgiving answer
Culled from the heart of the matter of splatter
