Inspector Watson of Scotland Yard needs the guests' help this evening to solve the curious murder of an eccentric Scottish lord. The case must be reopened, and the perpetrator tracked down through clever deduction.

With the active participation of those present, the circumstances of the murder and the crime scene will be reconstructed.

At the end of the investigation, those detectives who have solved the case correctly are rewarded with a small prize by Inspector Watson. In terms of costumes and props, this murder mystery dinner is inspired by England in the 1920s and 30s. The picture is rounded off by elaborately designed pieces of evidence and investigative documents.
