A sleepy little village suddenly becomes the subject of gossip for all of England—of course, because something unheard-of happened here! The local scholar sent his assistant to Malta to buy a unique Peruvian mummy in a green sarcophagus. But when the professor opened the box, instead of the shipment he found the corpse of his assistant…
If only a great detective like Hercule Poirot had been nearby, he would have solved this riddle in no time. But no investigator could be found… The police admitted their powerlessness. Local residents set out to search for the truth: an eccentric professor with a barbaric servant, a bold officer, a quiet widow, a cocky adventuring sailor, a not-very-well-off artist—and that mysterious Peruvian who insists that blood of Inca kings runs in his veins… Who will be honored with revealing the crime that even Scotland Yard fled from?
