Measure for Measure — Act 4, Scene 1: The moated grange at St. Luke's.

At the moated grange, Mariana is waiting in the dark when the disguised Duke arrives and asks whether anyone has come for him. Isabella then appears and tells him the details of Angelo’s private garden, the gate she can use, and the midnight meeting she has promised Angelo. The Duke brings Mariana in and introduces her to Isabella, explaining that Mariana should help with the plan. Isabella and Mariana speak privately, and Mariana agrees to take part if advised. The Duke reassures them that Angelo is still Mariana’s husband by pre-contract, and he leads them away to carry out the scheme.
