The Tale of the Unknown Island by José Saramago

Senhor José slept like a log. After returning from his dangerous but successful visit to the unknown woman's parents, he wanted to set down the weekend's extraordinary events in his notebook, but he was so tired that he didn't get any further than his conversation with the clerk at the General Cemetery. He went to bed without any supper, fell asleep in less than two minutes and when he opened his eyes, at the first light of dawn, he discovered that, without knowing how or when, he had made the decision not to go in to work. It was Monday, the very worst day to miss work, especially if you were a clerk Whatever the alleged reason, and however convincing it might have been on any other occasion, it was always suspected of being merely an excuse, a way of justifying prolonging the indolence of Sunday into a day that was legally and customarily devoted to work.

After the repeated and increasingly serious irregularities in his behaviour since he had started looking for the unknown woman, Senhor José is aware that not going to work could be the last straw as far as his boss's patience was concerned. This frightening prospect, however, was not enough to shake the firmness of his decision. There are two important reasons why Senhor José cannot postpone what he has to do until he has an afternoon off. The first of these is that, one day, the mother of the unknown woman will come to the Central Registry in order to recover the keys, the second is that the school, as Senhor José knows all too well, from harsh experience, is closed on the weekend.
