There’s a new student at the Legatum Continuatum School for the Descendants of Famous Detectives and Amanda is supposed to work with him. Scapulus Holmes is a descendant of the great Sherlock and he’s crazy about her. Unfortunately she thinks he’s a loser and would rather die than have anything to do with him. But when the kids discover a dead body encrusted with strange living crystals, Amanda realizes she needs Holmes’s help. If the crystals fall into the wrong hands they could be used for nefarious purposes, and only he knows how to protect them. Can the detectives keep the bad guys from learning the crystals' secrets? It would help if they could figure out who the dead body is too. Only if Amanda and Holmes can find a way to work together can they prevent a disaster, and it isn’t looking good.
