In March 1847 the world first read of Mr Toots saying: ‘It’s of no consequence.’ He went on saying it for the next 13 months until the last number of Dickens’s Dombey and Son had been published. His embarrassed sallies into affairs of the heart had gained a catchphrase. Mr Toots’s remark meant ostensibly, ‘It doesn’t matter,’ but I was reminded of it by the warning that the United States issued after the killing of three of its service people in Jordan.
