'There should be no combination of events for which the wit of man
cannot conceive an explanation.'
In this tale drawn from the note books of Dr Watson, the deadly hand of
Professor Moriarty once more reaches out to commit a vile and ingenious
crime. However, a mole in Moriarty's frightening criminal organization
alerts Sherlock Holmes of the evil deed by means of a cipher.
When Holmes and Watson arrive at a Sussex manor house they appear to be
too late. The discovery of a body suggests that Moriarty's henchmen have
been at their work. But there is much more to this tale of murder than
at first meets the eye and Sherlock Holmes is determined to get to the
bottom of it.
