‘Before forensics, DNA, and CSI we had dollhouses – an unimaginable collection of miniature crime scenes, known as the Nutshell Studies of Unexplained Death. Created in the 1930s and 1940s by a crime-fighting millionaire heiress grandmother Frances Glessner, the Nutshells helped homicide detectives hone their investigative skills. Despite all the advances in forensics, the Nutshells are still used today to train detectives.’ - Of Dolls and Murder
