(Comedic Farce) Move Over, Mrs. Markham is set in a very elegant top floor London flat, belonging to Philip and Joanna Markham. The flat has been under renovation, and thus has been largely empty. Philip is a straight-laced publisher of children’s books, and he shares an office with his partner, Henry Lodge, on the ground floor. Reluctantly, Philip agrees to let Henry borrow his apartment for the evening to “entertain” his latest girlfriend. At the same time, Joanna Markham is persuaded by Linda Lodge to let her borrow the apartment, so she can entertain her lover. What nobody knows is that the flamboyant interior designer who had been decorating the apartment for the past three months has plans of his own! When all three sets of people converge on the apartment, expecting to find it empty, chaos and confusion ensue.
