Jones’s well-known technical knowledge and his powers of minute observation have enabled him to prove conclusively that the miscreants could not have entered by the door or by the window, but must have made their way across the roof of the building, and so through a trapdoor into a room which communicated with that in which the body was found. This fact, which has been very clearly made out, proves conclusively that it was no mere haphazard burglary. The prompt and energetic action of the officers of the law shows the great advantage of the presence on such occasions of a single vigorous and masterful mind. We cannot but think that it supplies an argument to those who would wish to see our detectives more decentralized, and so brought into closer and more effective touch with the cases which it is their duty to investigate.”
