I just watched an episode of “Timeless” about Mary Grace Winterton. She’s been referred to as “Mrs. Sherlock Holmes” — a female investigator on the New York police force before women even had the right to vote

They could build a whole series around her. Sort of a Sherlock meets Bramwell but set in 1910s USA.
