JM: These relationships between calendar
days, characters and real people are sometimes puzzling. Without checking
it in the text... didn't Demon's airplane crash in April 23?
Jansy,
You must be thinking of Andrey Vinelander who dies on April 23, 1922. Demon
perishes in an airplane crash in March, 1905. (It is always better to check
in the text:)
best,
Alexey
