Key passages
“The discovery of the knife in the pocket of Mr. Copperdock’s overcoat, combined with the fact that although Dr. Priestley and Mr. Ludgrove had each received a numbered counter, they had not so far been menaced by any particular danger, had convinced the police that the secret had died with Mr. Copperdock.”
The police concluded that Copperdock was the murderer and that the case was closed because the knife had his fingerprints and no further threats occurred.
