Yesterday, after reading through the violin part of Cyril Scott's Violin Sonata (written in 1908, and dedicated to Ethel Barns), I grabbed my copy of Scott's Music: Its Secret Influence Throughout the Ages in search of some reference to Barns. I first read the book when I was at Juilliard after it was recommended to me by David Diamond. I found a first edition somewhere, and I read its rather "over the top" insides once in a while. I happened to notice the inscription inside the cover, which is clearly written in the hand of an older person. There is some reason to believe that it might be the hand of the 70-year-old Ethel Barns, considering the initials.
The "Hollywood" puzzles me. Barns could have been in Hollywood in 1944 (we know so little about her comings and goings). There's also the matter of the code below the inscription: Tol0 (I can't figure out how to type a zero with a slash through it).
