Priestley accepts, visits Ludgrove's shop, and while waiting alone, is confronted by the Black Sailor.

## Key lines

> 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.

_Summarizes the official police theory that Copperdock was the killer and his suicide ended the mystery._

> If I am correct in my deductions from the new evidence which has come into my hands, I can prove beyond question that Mr. Copperdock was innocent, indeed, that he himself fell a victim to the agency which committed the other murders.

Ludgrove claims to have evidence that Copperdock was not the murderer but another victim of the same killer.
