Mum knows

As term went on, Rufus made it his business to track down his absent father. This wasn’t easy if, as he did, he wanted nobody to know. He got the answer via his mother, who needed his father’s address for her solicitor and to forward any other mail she felt inclined to send on, which for some odd reason meant all of it! ‘Silly woman!’ thought Rufus.

He found the address surreptitiously one weekend when he went home, ostensibly to see his mother. Rufus got the impression, from his mother’s outbursts, that his father was 'shacked up' with another woman.
