The two young brothers of the Oberon family live in their mansion with one faithful butler. They are happy until they discover the inheritance has gone to cousin Toni. This charming girl is shortly to descend on them, and the problem that faces the two is "Murder or Marriage?" When Toni arrives they have to consider whether (if murder) the means shall be the knife, or poison, or the dungeons, or (if marriage) which of the two is it who must marry her? Ian Stuart Black plays every conceivable variation on the alternate plots of the brothers, and the play is alive with wit and invention.
