You really have to wonder what Harry and Meghan, hunkered down in their Montecito wellness bunker, currently make of the reaction to Harry’s memoir Spare, which has been leaked to the world over the past few days. So far the book has made headlines for Prince Harry’s tales about losing his virginity in a field next to a pub (and being subsequently slapped on the rear by the older woman), his frostbitten penis, talking to a bin after taking magic mushrooms and a scrap with his brother that led to him falling on a dogbowl and breaking his favourite necklace.

Mr S gets the impression that this isn’t quite the dignified, progressive image of a rival King and Queen across the water that Meghan has been aiming for with her insufferable Archetypes podcast.

But what really stands out from the extracts published so far is how petulant the princeling comes across in his anecdotes, whether he’s complaining about the size of William’s bedroom as a child or blaming Will and Kate for him wearing a Nazi uniform to a fancy-dress party aged 20 (the poor prince was just following orders, apparently).

In fact, Harry comes across so poorly in the book that you do have to wonder if even his own ghostwriter holds a low opinion of him. As if to confirm this, Mr S notes that a Twitter account that appears to belong to the writer, J.R. Moehringer, has recently liked a tweet that said of Harry, ‘It is all me me me’. The tweet was a reply to Spectator Chairman Andrew Neil, who pointed out that ‘Harry’s claim that he killed 25 Taliban is a nightmare — an absolute nightmare — for his security teams.’

Moehringer is a former Pulitzer winner who is known for writing Andre Agassi’s revealing autobiography in 2009. And he will certainly have come to know Harry well in the course of writing Spare.

When writing Agassi’s book the ghostwriter apparently moved to Las Vegas for two years into a house a mile away from the tennis star’s. Phil Knight, a founder of Nike who Moehringer also ghostwrote for, said ‘he gets you to say things you really didn’t think you would’ and described him as ‘half psychiatrist’. No wonder Harry felt so comfortable opening up.

Could it be that even after spending days with Harry that the ghostwriter was not exactly impressed with the royal?

A slip of the thumb from the Moehringer account no doubt…
