Why do we read biography? Why do we choose to write it? Because we are human beings, programmed to be curious about other human beings, and to experience something of their lives. This has always been so - look at the Bible, crammed with biographies, very popular reading.

'Words and Music' on Radio 3 is always a treat. Actors read passages of poetry and prose interspersed with music, and nobody tells you what it is. Later you can look it up online, but at the time you can't cheat.

'Great Expectations' has been described as 'Dickens's harshest indictment of society.' Which it is. After all, it's about money. About not having enough money; about the fever of the getting of money; about having too much money; about the taint of money.
