When the Crown Prince of Austria is found dead, the evidence, as construed by Inspector Lestrade, points to suicide.

But Sherlock Holmes deduces that the prince has been the victim of murder - a murder that is only one piece of a larger and much more portentous puzzle, designed by one Professor Moriarty.
