The knight's tour is the old puzzle of walking a knight across every square exactly once, and Jordi Fernández's fragrance for Mind Games works the same seam of hidden geometry. Cedrat, nutmeg, saffron and ginger open it, cedarwood and lavender hold the middle with gardenia for cream, and benzoin, vetiver, oakmoss and cashmeran carry the trail. The house files it as a woody fougère, and the spine is exactly that.
