I don’t know if you’ve seen monsters in London, but there are monsters. No one knows when they appeared.

What is certain is that they have been around longer than humans. The growth of the city has left them feeling somewhat overwhelmed, but they have found their new ways of surviving.

The monsters are planning a big project. They are going to free the ravens from the Tower of London. Over the centuries they have tried countless times to enter the Tower of London, and each time they have failed. This time they wanted to use the gravel from the Thames to make Primrose Hill higher and higher, so that Little Peng could glide silently on the wind to the Tower of London five kilometres away. They had learnt from the Great Fire of London: once the little Peng arrives, it would set the Beefeater's Lodgings on fire. The other monsters then take advantage of the confusion to free the ravens. Of course, it doesn’t work. For Primrose Hill hasn’t grown one centimetre since the beefeaters discovered their plan. For hundreds of years, the beefeaters have sneaked the gravel back into the Thames in every daytime.

We all need the ravens.
