The Specialists officially investigate a 'wax corpse', an 'inverse mummy' which result not from oxygen deprivation but from immersion. Ferdinand Wagner, the new chief of the whole LKA (state prosecution department), who intends to close the expensive 'cold case unit'. While the section captain deals with him, the team detectives focus on the payment of the counterfeit ransom for Katrin Stoll to Jürgen Zoch. But the fiend got wind of his turned mole and prepared a spectacular diversion, with a trap corpse, so several team members find themselves in unexpected physical danger and Henrik must improvise quickly.
