Travels with My Aunt book by Graham Greene

"I met Aunt Augusta for the first time at my mother's funeral..."
 
Described by Graham Greene as "the only book I have written just for the fun of it," Travels with My Aunt is the story of Henry Pulling, a retired and complacent bank manager who meets his septuagenarian Aunt Augusta for the first time at what he supposes to be his mother's funeral. She soon persuades Henry to abandon his dull suburban existence to travel her way—winding through Brighton, Paris, Istanbul, and Paraguay. Through Aunt Augusta, one of Greene's greatest comic creations, Henry joins a shiftless, twilight society; mixes with hippies, war criminals, and CIA men; smokes pot; and breaks all currency regulations.
