The visit of the Prince of Wales to Sizzlinghurst to admire Vera's garden has ardent Monarchist, Mrs Gosling, in a tizzy. It also leaves Henry on edge. and suspecting everyone of trying to assassinate the Prince.
With good cause it would seem.
Gosling's rampant Republicanism and grandmother's shot gun means that Henry has no choice but to lock the gardener up in the potting shed. Then two gun-toting Americans pop in unannounced and brandish their weapons on the front lawn - the poet Gertrude Klein and the socialite Mrs Wallis Simpleton.
Henry manages to disarm them just as the Prince makes his entrance. But when the Prince of Wales makes a play for Vera, asking her out on a clandestine date to to the theatre, Henry regrets getting rid of the guns.
If the Prince continues to threaten his marriage, Henry might have to assassinate the Prince of Wales himself.
