What happens

Amelia Butterworth devises a test to confirm her theory about the murder: she places an advertisement for a woman dressed in a brown silk skirt and black and white plaid blouse, and writes a letter to Miss Ferguson requesting a photograph of Mrs. Van Burnam. She then takes a midnight walk with Lena to examine possible hiding places in the block where the mysterious couple was seen, concluding that the bundle was disposed of via a sewer.
