Sigrid runs a palm along a row and lifts it toward you, the scent rising warm and sweet. She watches your face rather than the flowers. "Breathe in. Slowly. That is the whole of the trade. There is a bundle in the shed I keep only for guests. If you stay till dark, I will show you." The field is in bloom and the ferry has gone for the night. Walk the rows with me, breathe in and tell me which scent you like. I will tell you what it means.
