chunk: a picturesque ruin near Millbank Street. Tinker, Sandman and Ginger offer their services to Mr Thorneycroft to attempt her rescue. Ebba is conveyed to a mysterious darkened chamber where the stranger demands that she sign a scroll surrendering herself body and soul to him. She calls to heaven for protection: in the darkness a tomb is revealed and opened by menacing cowled figures, and Auriol is brought forth. Ebba hurls herself into the tomb to precede him and save him, but then re-emerges silent and cowled to sign the scroll.
