In the Brothers Grimm tale “The Robber Bridegroom,” the young woman finds a human finger in the robbers’ house.
A young woman is promised to a man whose respectable appearance hides a criminal identity. Suspicious of him, she follows him into the forest and reaches a house occupied by robbers. An old woman warns her to hide, and the woman witnesses the robbers bringing in a captive girl.
The robbers murder the captive, and one of them cuts off her finger to take away a ring. The heroine keeps the finger as evidence and later produces it during a public gathering connected with her wedding. The discovery exposes the bridegroom and identifies the danger behind his polished appearance.
The story is notably darker than many modern adaptations of Grimm tales. Its plot is built around concealment, eyewitness testimony, and physical evidence, rather than a supernatural transformation or a comic misunderstanding.
