The past few years have been littered with surprises from the Duke and Duchess of Sussex.
Harry and Meghan have become expert in shaking things up, making unexpected decisions, rocking the boat.
Now add to that, the news that they are returning to live in the UK.
This has been a relatively sudden decision.
I've now spoken to people who know the couple well. Although there had been general discussions about the possibility of spending more time in the UK, the decision to move back was made recently.
The family's visit to the UK in July was significant.
As well as spending time with the King at Highgrove, Harry, Meghan and their children, Prince Archie and Princess Lilibet are said to have loved being with the family of Harry's mother, Diana, Princess of Wales.
The children met their aunts, uncles and cousins. The visit to Europe, which included time in Portugal, where they have a home, was described to me as "such a great time" for the family. It turned a possible move back to the UK into a firm decision.
I am told that this move is not due to any problems in the US. It has been driven by the couple's desire to spend time in Europe, nearer Harry's family and wanting to educate their children in the UK.
Schools have been chosen for Archie and Lilibet. New terms for virtually all schools in England start by the second week of September. The Sussexes will need to settle in so we can expect the family to be back in the UK within the next ten days.

The exact location has not been revealed but they will not live in London.
They will likely instead be swapping a multi-million dollar mansion in California for a slightly chillier prospect in the UK countryside.
The Cotswolds and Northampton area, close to the Spencer family estate, Althorp, are rumoured to be where they will settle.
Althorp House was the childhood home of Harry's late mother, Diana, Princess of Wales
