Despite Holmes' attempts to safeguard him, Openshaw meets a tragic end, drowned in a manner reminiscent of the other deaths.Holmes, however, manages to track down the ship responsible for delivering the fatal letters and investigates further to uncover the origins of the sinister plot. The story concludes with Holmes unraveling the connection between the deaths and the Ku Klux Klan, though Openshaw's death remains a somber reminder of the dangers surrounding the case of the five orange pips.
