This mystery centers on questions of authenticity, evoking paintings and antiques, as desire, appraisal, and deception intertwine. The title story won the All Yomimono Mystery Newcomer Award and was later included in a book of the same title.

At the boundary between genuine and false, desire and deduction begin to waver.

An early mystery by Osaka Go set in Granada, Spain. Later retitled Ansatsusha Granada ni Shisu, it already links the author's interest in Spain with the texture of hard-boiled crime fiction.

Against the city of Granada, a passion for Spain intersects with the tension of crime fiction.
