Asquith

Colonel Asquith was a British citizen, living in London in the mid-nineteenth century.

In 1868, his daughter Janice was to be engaged to a local businessman, Everrett Boyd. Asquith approved of the marriage, and was annoyed when his daughter had her doubts, and started visiting Thaddeus the Great in hopes of asking her deceased sister for advice.

Not long after, Asquith was confronted by Jacob or Evie Frye, who investigated Thaddeus' murder. While Asquith wasn't saddened by the news of Thaddeus' death, he turned out to be innocent of the crime, which had been committed by Douglas.
