Page 344 "They called him 'Our Man in Havana."

From page 344 of the book:  Regretfully, I listened as Owen joined them, dealing the cards, winning pot after pot of chips, relating episodes of his childhood and his adolescence, especially those incidents concerning the discovery of sex and the failure of love. They were full of disappointment and unrealized expectations. He talked of injured cousins, divorced aunts, infant deaths, business failures, heart attacks, teenage abortions, and friends' cancer. The old men hooted and howled and begged him for more. They called him 'General.' They called him 'Professor.' They called him 'Our Man in Havana.' Whistles by the old priest nearly shocked me to sobriety. Revenant grasped Owen's hands and said to him:
"Do your best, my friend. We ask only that you do your best. Don't be afraid."

Clockwise from top left: Cover for the novel "Our Man in Havana" by Graham Greene; Graham Greene, 1904-1991, English author, playwright and literary critic; Book cover photo of Greene's "A Life in Letters"; Alec Guiness as James Wormold in the movie version; movie poster; scene from the movie with Alec Guiness and Ernie Kovacs (Captain Segura).

The black & white film version of this book, which I actually just saw a couple days ago, is incredible.  Produced & Directed by the great Carol Reed (if you don't recall Reed, he did "The Third Man"), its comedy is brilliantly entwined with its suspense, all fixed against the shadows and strange sources of light of Reed's view of pre-Reveolutionary Cuba, although the movie was filmed just after Castro overthrew the government of the previous dictator.  I highly recommend this film.  It's available from Netflix.  And one more thing, Ernie Kovacs does a stupendous job, as does Noel Coward.
