Face Down among the Winchester Geese (Lady Appleton Series #3)

Susanna, Lady Appleton, wants only to tend to the medicinal herbs in the garden of her London townhouse. But when a gentlewoman is found murdered in the brothel district, a single goose feather left near the body, Lady Appleton is forced to investigate. Uncovering a string of similar killings from the past, Susanna finds that nobody, not even her own husband, is above suspicion.
