During one of her visits to Major Trevor on behalf of her father, Eugene discovers the rendezvous and, consumed by fury, rushes to Trevor's residence. Despite Enid's efforts to warn Trevor, she arrives too late; Eugene fatally shoots her and then takes his own life. However, before his demise, Eugene falsely accuses Trevor of the crime.
