I'm very curious to know which biography says that Barrie visited Michael's grave "every day he was in London" - meaning for the rest of his life?? I can find no mention of it in Mackail, the only reliable biography in Nico's opinion when it comes to facts. Nico certainly never mentioned it to me, which seems odd given that he lived with Barrie "off and on for more than 20 years". Barrie was often referred to in the press as "the hermit of the Adelphi". He didn't drive and had no chauffeur, so the idea that he made a daily (or nocturnal?) pilgrimage from the Strand up to Hampstead churchyard also seems a little far-fetched. But of course such visits - if true - would "very important to the life of Sir J. M. Barrie" -- did I suggest otherwise?
Yes, Nico came down to London from Eton, but no, he did not go to the funeral. If you check his letters to me (published on this website) he says "I was discouraged (praise the Lord!) from going to the funeral and went to stay in Cannon Hall with the du Mauriers — about half a mile from the church."
