Three imprudent explorers, venturing in a cave, become active players in a devious case of homicide. The case, conducted by Chief De Narwhal and his spouse Melody De L'Eel, is accurately reported in the journal of a young narrator, who emphasizes its contradictions: the cave, a most famous opening named "The Vulva" (due to its striking resemblance to the womanly pudental), is the scene of a heinous betrayal, which might possibly explain the reason behind the decease under investigation. In the course of the trial, in which many highly-qualified experts are implicated, first and foremost the philosopher Alan Brown (aka Galactic of the Galactics), a few legends regarding adultery and female betrayal are decisive, which will be crucial in guiding our narrator and his partner through the early phase of exploration in "The Vulva" and catapult him into a universe particularly out of reach, though "incredibly and blatantly rich".
