The December 21 1935 edition of the Toronto Daily Star included this notice of a travelling evangelist who was about to speak in a local church:
Many evangelists led a less than exemplary life before finding God, but Mattie Howard was an extreme example of this. Born in 1894, Ms. Howard was convicted in 1919 of second-degree murder. At the time, she was dubbed “The Bandit Queen of Kansas City”. During her murder trial, she met Irish president Eamon de Valera.
Paroled after seven years for good behaviour, she became a touring preacher. In 1937, she wrote her autobiography, The Pathway Of Mattie Howard, To And From Prison: True Story Of The Regeneration Of An Ex-Convict And Gangster Woman. The Goodreads web site has a listing for it, including one favourable review.
