Another dark picture

I met a pal at the world famous Inn today, mainly to talk about rock music, and books about The Beatles. Like me he has consumed a few of them. At the moment I am reading Julia Baird's biography. She is the half sister of John Lennon. Crucially she grew up with John's mother, Julia, whereas he only did intermittently. On the way home, along the towpath, I took this picture.
