New to me

Whilst recycling some old newspapers, a headline from around Remembrance Day caught my eye. One describing the Unknown Warrior as a hero. But if he’s unknown, how could the writer know that the dead guy wasn’t a right villain?
    “It’s just T.U.B., mate,” I was told. “Stuff made up as routine puff. The Usual Bollocks.”
    There’s a lot of it about. Especially in London.
