In a play by this author, the art dealer Ernest Friedman declares he could “never understand this disgusting three-sided erotic hotch-potch” after finding his wife with a pair of characters originally played by this author and his friend Alfred Lunt. That play by this author depicts the bisexual love triangle of Gilda, Otto, and Leo (-5[1])and is titled Design for Living. A character in another play by this author who is called “feckless, irresponsible, and morally unstable” torments another character with a (*) floating vase and is summoned by Irving Berlin’s song “Always.” (10[2])In that play by this author, Ruth is killed in a car crash after Madame Arcati conducts a séance which inadvertently summons Charles Condomine’s deceased wife Elvira. For 10 points, name this British playwright of Blithe Spirit. ■END■ (10[1]0[3])
