From Amazon.com.au:
Two prostitutes have been murdered in Tokyo.

Yuriko had been working as a prostitute all her adult life, starting while still at school, where her stunning beauty compensated for what she lacked in intellect and commanded attention from older men. Kazue worked for a blue-chip company and had good career prospects, but was unpopular with colleagues and felt isolated. She chose to walk the streets at night where she hoped to get noticed.

Twenty years previously both women were educated at an elite school for young ladies, and both exhibited exceptional promise prior to their brutal, unnecessary deaths.

How and why did this tragedy occur? With narration from Yuriko's embittered, unattractive sister and through the girls' journals and diaries Kirino allows their shocking story to unfurl.
