A body is found that shows all the hallmarks of having been murdered. The detectives investigate and find the usual array of suspects. However, as the investigation goes, the case makes less and less sense. All of the suspects have alibis; evidence that first pointed one direction actually points somewhere else on closer examination; some evidence makes no sense at all; etc. Eventually the truth is revealed: the victim was not murdered at all, but died in a freak accident (sometimes of their own making) that caused their death to look like a homicide.
Can be a Karmic Death.

During one of his assignments, something goes wrong and an actual freak accident results in one of his men being run over by a bus.

His obsession drives him into paranoia, but as the viewer learns there never was a conspiracy, this really was just a freak accident.

- In one of the later Biggles short stories, the veteran pilot, now a policeman, is asked for his opinion on the death of a girl who had previously had an argument with her pilot boyfriend. She was hit on the head with a blunt instrument and died instantly. The boyfriend is being sought. Biggles reviews the case. The girl was found dead in her garden with no signs of intrusion or struggle. No weapon has been recovered. However, in the photographs is an unopened box of chocolates. Biggles asks about this. It has been disregarded by the police as of no significance, incidental. He asks if this was kept, and discovers one corner of the box is badly crushed out of shape. Then it becomes clear. The pilot boyfriend sought to make up the row with a romantic gesture, dropping a box of chocolates to her in her garden from several hundred feet up. He just aimed too well. Biggles notes it would be like hitting her with a brick, and points to people being killed in the wars by shrapnel, parts of damaged aircraft, or even spent bullet cases dropping from the air. The case now becomes not murder, but death by misadventure.
