Dot was born in Little Hangleton in 1917 and had known Franklin Bryce since they were children. She seemed not to have fond memories of him, stating that he had a horrible temper and backing up her statement with childhood recollections.
By August of 1944, Dot was still living in Little Hangleton and frequented the village pub, the Hanged Man. One night in that time, the Riddle family were found dead in their drawing room and the entire village turned up to discuss the murders, drink and gossip. When the cook turned up and announced that Frank Bryce had been arrested, Dot stated that Frank had had a horrible temper and that she wouldn't want to get on the wrong side of him, and began reminiscing about things that had happened in their youth.
