You should remove season 5 since the show got cancelled after season 4.
Showlist is incorrect, there are 6 episodes in series 1:
01 Borkmann's Point (Borkmanns punkt)
02 Münsters Case (Münsters fall)
03 Moreno and The Silence (Moreno och tystnaden)
04 The Swallow, The Cat, The Rose & Death (Svalan, katten, rosen, döden)
05 Carambole (Carambole)
06 Case G (Fallet G)
Whatever you do, don't waste time watching this show. The 24 episodes work towards a cliffhanger to season 2, which looks promising if this genre is your thing, however that 2nd season was never made since the show got cancelled.
