Summary Georg Ritter, owner of luxury stud farm "Ritter", was skull-smashed. Fresh widow Dana Ritter points commissioners Hofer and Bach to horse trainer Markus Köhler, fired by Ritter after objecting to the million Euros sale of champion horse "Diamonds Quest" which Köhler can no longer ride and win lucrative prize money with, half for him, co-owned by Julian Rabe, who was cheated out -although he denies so- of half of the ten percent extra 'under the table'. Dana Ritter knew about Georg's affaire with Evi Ahrens, Markus Köhler's partner, the estate's financial manager. Marie still can't fully committee to her new duties on alderman Clemens Roth's department, as Achtziger finds her music academy successor unavailable and the benefit concert star violinist insists on Marie so measures are take. Bach finds his new apartment financially unacceptable, but puts off telling Sandra Mai he'll remain her housemate longer then either likes.
