It was the 21st of December 1908 in Glasgow’s Square Mile of Murder. At 7pm young maid Helen “Nellie” Lambie left the flat where she worked for Marion Gilchrist, leaving her 83-year-old mistress in the flat at 15 Queens Terrace, West Princes Street. Nellie left every day at 7 to fetch the newspapers for Miss Gilchrist, a task that usually took her 10 minutes. It was during this short period of time that Nellie Lambie was running errands that her wealthy employer was murdered, and an injustice of historic proportions was set into motion. But we’ll get to all that. This is Square Mile of Murder, and today we’re covering the final case from our namesake, the the murder of Marion Gilchrist and the trial of Oscar Slater.
