Muriel Spark at a party in the 1960s.
Parties were a key element of the New York social scene.
Muriel Spark's diary entry of 14 June 1966 records that she accompanied George Nicholson to the PEN ('Poets, Essayists, Novelists') party.
Also at the party was the playwright Edward Albee, best known for writing 'Who's Afraid of Virginia Woolf'.
Nicolson, of Dell Books, NYC, was one of Spark's closest New York friends, and a frequent companion.
