The Driver's Seat by Muriel Spark

The Driver’s Seat, Spark’s own favorite among her many novels, was hailed by the New Yorker as “her spiny and treacherous masterpiece.”

Driven mad by an office job, Lise flies south on holiday — in search of passionate adventure and sex. In this metaphysical shocker, infinity and eternity attend Lise’s last terrible day in the unnamed southern city that is her final destination.

Muriel Spark (1918-2006) was the author of dozens of novels, including The Prime of Miss Jean Brodie, Memento Mori, A Far Cry from Kensington, The Girls of Slender Means, The Ballad of Peckham Rye, The Driver's Seat, and many more. She became Dame Commander of the Order of the British Empire in 1993.
