With several witnesses from London, including Sir Bernard Spilsbury, the trial of Roger Vernon and his 25-year-old mistress, Suzanne Bertron, for the murder of "Red Max" Kassel opened in Paris. Kassel, notorious figure of the Paris and London underworlds, was found riddled with bullets beneath a hedge at St Albans in January last year.
