Sinclair Lewis 
Innocents: A Story for Lovers 

An elderly, modest New York couple, 'young-hearted old lovers, Mr. and Mrs. Seth Appleby’, decide on a whim to risk their life savings on opening a roadside cafe in seaside New England. It doesn’t work out, but that’s just the start of their misfortune. The Innocents (subtitled 'A Story of Lovers’) features an unlikely romantic pair of sexagenarian Johnny Appleseeds in a sweet story awash with obvious pathos, artfully offset by the gently ironic air of the author, Sinclair Lewis.
