Truce. The Diary of Martin Santome, Paperback/Mario Benedetti

Forty-nine, with a kind face, no serious ailments, a good salary and three moody children, widowed accountant Martin Santome is about to retire. He assumes he'll take up gardening, or the guitar, or whatever retired people do. What he least expects is to fall passionately in love with his shy young employee Laura Avellaneda.
