Lines from Bob Marley songs that were written for him by a middle-class Englishwoman.

• Don’t you worry about a thing
• There is one question I’d really love to ask
• Stand up for your rights!
• I hope this jam is going to last...

Not to mention the spin-off series about her brother Rhodes.

You know how sometimes you see a sign that suddenly inspires you to write a whole series of adventure books for children? Oh, don’t you? Well, to be fair, neither did I until ten minutes ago. But as I looked at that sign; like JK Rowling on that train journey, or Joe Craig after his usual pre-book pint of margaritas, inspiration struck; and my heroine leapt fully-formed into existence – the impetuous Irish-Italian girl detective, and the dare-devil adventures that lead her mother to exclaim the title of, let us say, the fourth book in the series: ‘Please Take Care, Piazza Slippery!’

Job done.

Sign at till at the British Library cafe:

"Due to a new credit card terminal installation, we are not able to process any payment by cards."

Right. Frankly, I'd have been tempted to stick with the old terminal.
