On a brisk Sunday morning at around 10am, as we wind our way around the grounds of the Tower of London, a boy, not more than ten years of age, hails Wiggins with a message:

My dear friends, Oliver Stone was found dead in his home. I think it might be instructive for you to look into this matter. Meet me tomorrow afternoon at 221B to compare our respective investigations, if you wish. S.H.

So begins "The Oliver Stone Case," a single extra case expansion originally published in Role Mag' (#3 - November-December 1990).
