Joe is suspended with pay pending investigation of the luckily not life-threatening shooting of his buddy and as turns out self-righteously overzealous informer Karl 'Schrotti' Schrothmann. Kaiser personally teams up with Rico to investigate the nocturnal bleeding to death in his own workshop of Stuttgart's loner world-renowned doll-repair-expert, who has a finger cut off, apparently to force him to tell the combination of his safe, which was not robbed of its treasure, a doll after the childhood likeness of emperor Wilhelm II. He was found by ex-con deliveryman Uwe Hehn, who helped himself to something, and had a doted, devoted teen apprentice, drop-out David Engstrom, whose businessman father owns the building and was desperate enough for his 'last heir' to blackmail janitor Florim Berisha into scaring off the 'unsuitable' mentor, whose business barely made break-even. Then another doll is found to contain an interesting candid video, opening new possibilities, as does the forensic finding that the finger was cut twice and a painkiller swallowed.
