The Murders in Praed Street · Chapter

VII: The Black Sailor explained

Inspector Whyland struggles to find leads in the murder of Richard Pargent, interviewing Ludgrove and the Pargent sisters without success.

What happens

Inspector Whyland struggles to find leads in the murder of Richard Pargent, interviewing Ludgrove and the Pargent sisters without success. He theorizes that the same hand killed Tovey, Pargent, and possibly Colburn, but motive remains elusive. That evening, Mr. Copperdock claims to have seen the black sailor near the Cambridge Arms, but Ludgrove casts doubt on his reliability. Whyland considers the possibility that Copperdock himself might be the killer, driven by an imitative impulse.

Themes in this chapter

  • The Psychology of Fear

    Copperdock's terror upon seeing the black sailor and his excited state reflect the psychological impact of the murders on the community.

  • The Role of the Detective

    Whyland's strategic interview with Ludgrove and his theorizing about Copperdock as a suspect illustrate the detective's methodical approach and reliance on psychological profiling.
