 are summoned to Warren’s cabin, where they find its occupant nursing a wounded cranium and thoughts of vengeance.It seems that Warren inadvertently brought some reels of film on board showing his uncle, near the end of a long dinner party, making an extremely impolite speech about his fellows among the world’s mighty, and that someone has just broken into Warren’s cabin, hit him over the head, and stolen enough of this film to cause unheard-of scandal.The four of them soon learn that a notorious and dangerous criminal (the “Blind Barber” of the title) is believed to be on board the ship.
