Morgue Drawer Books in Order

Cologne coroner Martin Gansewein discovers that he can hear the ghost of car thief Pascha. Convinced his death was murder, Pascha pressures the reluctant doctor to investigate, drawing them into the city's sex trade and car smuggling.

Martin returns to work expecting continued interference from Pascha's ghost, but another spirit needs help. Sister Marlene suspects that the fire at her convent was deliberate, drawing Martin and his girlfriend Birgit into a new investigation.

Martin hopes to spend time with his girlfriend, but Pascha's ghost keeps interrupting. When bodies discovered in a cemetery are found to have missing organs, the coroner and his unwanted companion become involved in another dangerous investigation.

Pascha encounters the wandering spirits of four children left in comas after a crash. With the teacher who drove their van missing, the ghost finds himself investigating the accident while managing an unexpectedly demanding group of young companions.

Reporter Susanne Hauschild is found dead, and her detective ex-husband becomes a suspect. While Martin is occupied with his pregnant girlfriend, Pascha investigates, following connections between suspicious deaths at a retirement home and a disreputable nightclub.
