Hardly a day goes by when I don't receive at least two emails at email@example.com
containing further revelations about the Humes and the Costins. They come from all over the world. Your views about the book, and the information you send, are very important to me, so please keep them coming, wherever you are!
Most recently I received an email from a versatile young violinist and violin teacher, Laura Riley, who lives and plays in Dubai. On a visit to the UK this year she visited a luthier in Oxford and bought violin made by Andrew Hume, Jock's father, in 1907.
'I absolutely fell in love with it,' she wrote. 'It has the most beautiful sound and enormous character.' My great grandfather would have been thrilled to hear Laura's endorsement of his theory that 'modern' violins had a finer tone than old violins like Strads.
Laura added: 'I was so saddened by the story of Jock that I decided to name my fiddle after him. I will take it back to Dubai with me, where I live and play, so the adventurous spirit of Jock will live on through this violin.'
Here is a selection from other recent emails.
