Mary Quinn

Mary Quinn, twin sister of Charlie, teaches English at a University in England. She was born in 1983, in Argentina, to Reginald and Abigail Quinn, during one of their travels, alongside her twin brother, Charlie. It was clear from an early age that the twins were destined for greatness. Less keen on travelling and adventure, Mary moved back to England at the age of 11, staying with relatives to get a high school education. During this time she discovered her passion for literature, and now teaches it herself. She is one of the sole reasons that Charlie decides to stay after his initial case in England is done.

Being a supporting character, Mary Quinn may make minor appearances throughout the series, if any.
