The Seven Great Detectives / 7人の名探偵

Yukito Ayatsuji’s The Decagon House Murders was published in 1987, and is credited with kick-starting the shin-honkaku (new orthodox) movement of murder mystery writing. Three (and a half) decades later, the genre is still going strong! There were several pieces and events in 2018 commemorating the 30-year anniversary of the influential work, and one of those was The Seven Great Detectives, a collection containing short stories from seven shin-honkaku writers.

The 8 Mansion Murders / ８の殺人

The title of The 8 Mansion Murders is way too generous; there's no way I'd rate it anywhere close to an eight. It's not particularly clever or inspired, but seems to think it's some sort of epoch-defining masterpiece.
