The Immortals' Investigator General's team continues their journey, this time not on the Royal Express, but on the cruise ship Colossal. A matter of national importance calls for heroes to a distant island state, in which a serious struggle for the throne flares up. However, many surprises await them along the way: they have to investigate the disappearance of a famous artist's mustache, the mysterious disappearance of a design engineer, the kidnapping of a noble lady. . .
And, of course, the case will not do without romantic adventures: the intern David will finally find out who his chosen one really is, and the doctor of the Undead will find his happiness.
