Recently, the Berryville Library purchased Rennie Airth’s John Madden mystery series. The first book in the series, River of Darkness, is set in 1920s England, when the specter of World War I still permeated the country’s psyche and Freudian psychological theories were still new and just starting to gain traction. In the novel, Scotland Yard Inspector John Madden is summoned to assist with the investigation of a shocking crime in a pastoral English village. Here, a local family has been brutally slaughtered, and the details simply do not add up for Madden. Several of his colleagues suspect the crime is the result of a robbery gone very wrong, but Madden thinks too many clues suggest that the murders were the killer’s (or killers’) focus.
