What is the setting of Cakes and Ale: Or the Skeleton in the Cupboard by W. Somerset Maugham?

Cakes and Ale is set primarily in England within two time frames. In the present time, narrator William Ashenden is a writer, not particularly in vogue, living in London in the twentieth century. Automobiles, buses, and telephones are in common use, and a reference to a 1921 Liebfraumilch being no longer available suggests late in that decade, but Marcel Proust is spoken of as still alive. No effect of the worldwide Great Depression that begins in 1929 are seen. Novelist Edward Driffield has been dead one year.
