He keys in a case where he had to track down a gang of three men who were suspected of a series of murders.  He does stumble on them, but they actually end up capturing him.  Fortunately, he was able to talk his way out of that predicament, and later on tracked them down again and captured them.  One was hanged for his crimes, while the other two were sentenced to twenty years in prison.
Little does Hilton know that two of his dinner guests, Edward Laverick and Edward Carter, are the two men who he sent to prison.

Initially, their plot seems successful, as the local constables who arrive to investigate the incident buy into the suicide scenario.
