A study in crimson

Now comes the big question about the reason for the murder. Theft was not the goal, because he did not lose anything from the house. Was the reason then politics or related to a woman? That was the question I faced. And I tended to the latter assumption, because political killers are happy to commit their crimes and then escape. But this crime is completely the opposite. It was deliberate, and the perpetrator left his traces all over the room, which means he was there the whole time. It must have been a personal mistake and not political, which called for such systematic revenge. When the writing on the wall was discovered, I leaned more towards my guess. But when the ring was found, I settled the matter. It became clear that the killer used it to remind his victim of a woman or someone absent.
