very big fan of ooyama's red museum, short stories all about cold cases, and the organization (of two people) that solves them. short thoughts on all stories パンの身代金 (Ransom of Bread): Case about a murder ocurring during a ransom handover, the solution is a trope that I think Ooyama likes to use, but it leads to a surprising solution, so that was fun. The motive, however, comes out nowhere and I can't imagine anyone actually deducing it. 復讐日記 (Diary of Revenge): My favourite of the collection. The Beast Must Die/For Yoriko style story about a man wanting to get revenge for his girlfriend, whose murderer he subsequently discovers and then kills. I was pretty sure I knew what the solution was going to be, but I got taken completely by surprise, and it makes a great conclusion. 死が共犯者を別つまで (Until Death Do We Part): It was at this point I was beginning to wonder whether I was reading a Norizuki book instead, because this is a story about exchange murders. After getting into a car crash, a dying man confesses that he was involved in an exchange murder (Ooyama does something similar in one of the Alibi Cracking stories) and the protagonist has to figure out which of two possible murders he was involved in. Story feels a bit bloated, because it has to give equal attention to both of these cases, as well as the exchange murder that the man benefitted from. This is another trope that Ooyama has used before, and it's pretty cool how it's used here, overturning the reader's base assumptions. My only minor niggle is 炎 (Fire): A girl's parents and her aunt are poisoned and then their house burned. There's some real cool reinterpration of events, and it makes for a dark ending. 死に至る問い (A Fatal Question): A murder from twenty-six years is replicated exactly, leading to a really innovative whydunit with an inspired idea at its core.
