Kate Warne: Pinkerton Detective
Written by Marissa Moss | Illustrated by April Chu
As Kate read the newspaper advertisement from the Pinkerton Agency for the third time, she knew that this was the job for her. It said: “Wanted: Detective. Must be observant, determined, fearless, and willing to travel.” But in 1856 no one would hire a single woman, so Kate decided to present herself as a widow.
Kate had been raised by her father, a printer. Books had always been her companions, and she knew how to make up a story—even the story of her life. “So Kate Carter became Kate Warne…exactly the kind of person you’d want to hire as a detective.” As soon as she walked through the door, Allan Pinkerton began writing down his impressions of Kate. He thought she was a client seeking help. From her manner and appearance, he knew he would take her case—whatever it was.
But when Kate told him she was applying for a job, he told her he “had no need for a washerwoman or cook.” Kate told him she was there to apply for the detective position. Pinkerton had reservations. The dangerous work was “not at all the sort of thing a woman could do,” he said. But Kate disagreed. She told him that she would be able to go into places his male detectives could not and could be the confidant of women witnesses. Pinkerton told her he would think it over.

The next day Kate was at the office as soon as it opened. “Today, you’ve made some history,” Pinkerton told her, “You’re now the first woman detective in the country.” He handed her a file marked The Adams Express Case. As she read the case, Kate felt a thrill of excitement. “The Adams Express Company transported money and valuables for businesses all over the South, by rail, steamboat, and stagecoach.” Valuables were well protected by locks that couldn’t be picked.
But $40,000 had disappeared. One suspect stood out from the rest—Nathan Maroney, the manager of the Montgomery office where the packages had come from. He had been the last person to lock up the carrying pouch before the messenger, Mr. Chase, transported it to Atlanta, where it was found to be empty. Maroney was arrested, but there was little hard evidence—only a slit in the pouch that had not been there before Maroney was accused.
Kate considered the problem then remembered the sleight of hand tricks huskers used to fool people. She figured out how Maroney had stolen the money, but they needed more evidence and a confession. While a male agent pretended to be a fellow thief named “John White” in the same jail cell as Maroney, Kate befriended Maroney’s wife, Belle, pretending to be Madame Imbert. While Belle didn’t confess to the theft, she did ask her new friend for advice on where to hide valuables. Kate told her she hid her valuables in the basement or buried them in the garden.

When Belle left town to visit her husband in jail, Kate took the opportunity to do some snooping at her house. Just as Kate found a freshly dug mound behind crates and barrels in the basement, she heard Belle returning home. She hurriedly put everything back in place and rushed upstairs. Belle was suspicious of the dust on Kate’s dress, and Kate knew she and the other agents had to act fast. She alerted another agent who crawled through the basement window while Belle slept. He tidied up the basement, and the next morning when Belle checked her hiding place, everything was in order. She could still trust her friend she thought.
The Pinkerton Agency plan was going like clockwork. Inside the jail cell, Maroney put his faith—and his money—in the detective’s hands. Maroney wrote to Belle, telling her that John White was going to help them. He instructed her to give John White all the money he had stolen. White was going to plant some of it on Mr. Chase, use some of it to bribe a judge to find Maroney not guilty at trial, and keep the rest for Maroney to collect later. At first, Belle didn’t trust John White, but one sentence from her friend “Madame Imbert” eased her mind and she went along with her husband’s plan.
As the ingenious plan was hatched and carried out, Kate made sure that all the money was secure. The money made its way to the Pinkerton agent “Mr. White” with Belle and Maroney none the wiser. As Maroney’s trial proceeded, and he heard Mr. White called as the first witness, Maroney suddenly changed his plea from “not guilty” to “guilty.” “The reputation of the Pinkerton agency was made. So was Kate Warne’s.”
Kate became one of the agency’s most valuable detectives. She was even put in charge of a women’s division and hired many more women who became “some of Pinkerton’s strongest agents.” But Kate Warne, the first woman detective in America, would always be considered the best.
