King Manjolo's Guest

When Jacobus, a scheming psudo itinerant missionary arrives in the resource endowed Bang’anja Kingdom, King Manjolo and his subjects are euphoric. Soon, death would be a scourge of the past for them. Jacobus has convinced them he is on his God’s mission to unravel the secret to eternal life for their king.
Manjolo believes knowledge of this secret will elevate his status to that of a god, and neighbouring kings and their subjects will supplicate before him for eternal life.
To unravel the secret, Jacobus requests unfettered access into the kingdom’s sacred carven shrine with diamond studded walls to harmonize his God’s endeavours with the Bang’anja’s.

Many before him have tried ingenious ruses to establish the location of the shrine and failed. Will the devious Jacobus succeed?
