The diagrams show that there are two different ways in which the routes
of the various persons involved in the Ravensdene Mystery may be traced,
without any path ever crossing another. It depends whether the butler, E,
went to the north or the south of the gamekeeper's cottage, and the
gamekeeper, A, went to the south or the north of the hall. But it will be
found that the only persons who could have approached Mr. Cyril Hastings
without crossing a path were the butler, E, and the man, C. It was,
however, a fact that the butler retired to bed five minutes before
midnight, whereas Mr. Hastings did not leave his friend's house until
midnight. Therefore the criminal must have been the man who entered the
park at C.
