Hiding in Plain Sight: Kate Warne and the Race to Save Abraham Lincoln

by Beth Anderson, Sally Wern Comport (illustrator)

America’s first female detective Kate Warne’s mission? Protect president-elect Abraham Lincoln from Southern rebels bent on assassinating him before his inauguration.

Abraham Lincoln faced a dangerous and uncertain future when he left Springfield, Illinois, for his inauguration in Washington, DC. Luckily for him, detective Kate Warne had his back, even if he didn’t know it yet.

Hired by the Pinkerton Detective Agency, Kate Warne used her exceptional acting and conversational skills to pose as a Southern lady to help uncover the rebel plot to kill Lincoln in Baltimore, the only Southern city on his inaugural train route to DC. Kate warned Lincoln’s staff that he faced a deadly welcome in Baltimore, the detectives urged him to change his route, but the president-elect refused to cancel his commitments. In a race against time, Kate and Pinkerton had one last chance. Lincoln would travel disguised as her sick brother on a night train from Philadelphia, secretly making his way through Baltimore in the wee hours of the morning and then on to Washington. Would they make it? Would someone leak their movements to the assassins?

This exciting American history picture book from award-winning author Beth Anderson, well-known for action-packed books on daring women, and illustrated by Sally Wern Comport in her signature mix of collage, drawing, and paint, brings Kate to thrilling and vivid life.

This is a very enlightening and moving account of Kate Warne's courage, insight and ingenuity in helping protect Abraham Lincoln from the assassination plot against him even before he was inaugurated as President. She is a woman to be admired and celebrated in American history. It may be a juvenile book, but it has a lot to say to us adults as well.

Need a great spy story? This is it!
Kate Warne, part of the famous Pinkerton Detective Agency, can go where male detectives can't go. Her ability to walk in places and converse with people where men rarely went allows her to help thwart a plan to assassinate Abraham Lincoln. Gorgeous, rich, detailed art complements the story, making it a true treasure! Bravo, Beth Anderson!

Every week I bring home twenty picture books to read and study. I only find a few that I consider truly worthy of a young child’s library. This week, Beth Anderson’s Hiding in Plain Sight: Kate Warne and the Race to Save Abraham Lincoln, was at the top of that list.
I love detective stories and mysteries. Hiding in Plain Sight is a historical story that includes a plot to kill the president, a real-life detective story, and a remarkable young heroine, Kate Warne. Just my cup of tea. Kate Warne was America’s first female detective, employed by the famous Pinkerton Agency. The book is a page turner for sure; we are always wondering what will happen next. Even young readers will likely know that Lincoln made it to Washington D.C. for his inauguration, but the mystery is “how.”
The pacing is perfect. There are punchy sentences and lots of page-turning phrases. When Kate is waiting expectantly for an answer to her letter, a single line – ‘A knock.’ -ends the page, keeping us captivated and turning those pages. Beth also asks lots of questions within the story, building suspense and keeping the readers engaged.
The scrapbook-like illustrations by Sally Wern Comport are detailed and evocative. They draw us in…and transport us back to the time period. We look and look again, each time seeing something more. So many good choices were made for the art. And, of course, Calkins Creek always does fabulous work with historical books. One of my favorite spreads is in Baltimore (I won’t say more – I want you to enjoy the surprise!) Everyone is illustrated in muted brown tones - except for Kate, standing apart in brilliant green.
The afterword shares Beth thoughts beautifully as well as giving lots of historical information. Beth writes about not underestimating someone based on appearances and giving up glory for the greater good.
Young readers will seek out this thrilling story of America’s first female detective again and again from their bookshelf. I’ve always believed the best books are for everyone. This one certainly fits that. My husband is a history buff and our good friend is an expert on Abraham Lincoln. I’m recommending Hiding in Plain Sight to both of them.

This is a spectacular book. Kids will love the intrigue and adventure. Teachers will love all the historical details, and parents and other adults will love all that and the fascinating illustrations on every page. It is easy to see how Beth and Sally poured their hearts into bringing us this gorgeous book that has shown light on Kate Warne, America’s first female detective. I had no idea that the Pinkerton Detective Agency had hired a woman to protect President-elect Abraham Lincoln when Southern rebels were bent on assassinating him before his inauguration. But Kate had his back even though Mr. Lincoln didn't know it then.

The Pinkerton Detective Agency hired Kate because of her exceptional acting and conversational skills to help uncover the deadly rebel plot to kill Abraham Lincoln in Baltimore. Kate warns Lincoln’s staff to change President-elect Lincoln's route and not go through Baltimore, the only Southern city on his inaugural train route to Washington, DC. But he refuses to cancel his commitments, so it's a race against time. Using disguises, false names, and the cover of darkness, Kate and the other Pinkerton detectives put their plan into action.

Readers will love how the fast train pace increases the urgency and pace, making the story feel almost like a thriller. I loved the details, such as the clocks, date headings, scenes, and words or phrases. Beth has provided an abundance of interesting facts in the back matter at the end of the book. She says, "Unfortunately, many of the agency’s records of this time were lost in a fire, so Kate Warne remains one of history’s fascinating mysteries."

Sally Comport's sepia-toned artwork immerses young and old readers in the book's drama. The framed pages, collage scrapbook style, detailed garments, and period furniture help show off the era. This very special book will be read over and over again, not only because of the story but also because it is such a feast for the eyes that children will love opening it up many times to see all the little details that beg to be seen again. Teachers will want to use it in their classrooms. Librarians will want to add to their shelves, and parents will want to pass this book down to their grandchildren. I wish you good luck with the book. Please let me know when the awards roll in.

Kate Warne is a fascinating topic for a biography, and I love that the details of her life are set against a pivotal moment in her career; the protection of President Abraham Lincoln as he traveled through Baltimore, Maryland on his inaugural train journey. Tensions were high, and whispers of a rebel plot to kill the president were heard by the Pinkerton Detective Agency, which had the presence of mind to have the talented Warne on its staff. Warne, who often disguised herself as Southern belle Mrs. Barley, in order to overhead Southern sentiments, was able to travel without detection, since no one expected a woman to be an operative. Along with the other staff, the agency was able to foil the plot to kill the president, so that he arrived safely to begin his term. There is an extensive afterword discussing facets of this journey, the state of detective work at the time, and the role of women during this era. There is also a complete bibliography.


The most brilliant part of this book is the artwork and design. Vintage photography, maps, and documents are arranged in collages that preserve the feel and colors of the Civil War era. There is so much documentation that exists from this time period, and it is used brilliantly in this book.


This is a picture book that is perfect for older children, and the story it tells is fast paced and exciting. It’s a good warm up for readers who might need a little coaxing to pick up Hannigan’s The Detective’s Assistant or Swanson’s Chasing Lincoln’s Killer, which are a bit longer.


Warne’s story is fascinating, especially since there were so few women who were able to work in fields like this.Brush off your spy skills by reading Hiding in Plain Sight along with Moss and Hendrix’s Nurse, Soldier, Spy: The Story of Sarah Edmonds, Kirkpatrick and Himler’s Redcoats and Petticoats, Wallmark and Smart’s Code Breaker, Spy Hunter: How Elizebeth Friedman Changed the Course of Two World Wars or even Christensen’s The Daring Nellie Bly: America's Star Reporter.

In February, 1861, president-elect Abraham Lincoln embarked on a 13-day inaugural train ride from Springfield, Illinois to Washington, D.C.  He had many stops scheduled along his route through the divided nation, but only one was in a southern state: Baltimore, Maryland.  Detective Kate Warne had reason to suspect an assassination attempt was planned for the Baltimore stop, so the famous Allan Pinkerton hired her to investigate and foil the plot.  Disguised as a southern lady, Kate was able to eavesdrop on ‘rebel talk’ to confirm her suspicions and share what she learned with Pinkerton.  Knowing that Lincoln’s route was unchangeable (“The only way to Washington was through Baltimore”), they had to find a way to get the information to Lincoln, convince him of its truth, and contrive a way to avoid a presidential detraining in Baltimore.  Kate raced to New York and Philadelphia to work with the president’s entourage, the railroad, and the telegraph companies to clear the way, knowing that Lincoln’s life was in her hands.

Students who know history will not be worried about the outcome of this story, but it is suspenseful and nerve-wracking nonetheless!  Short, unadorned sentences and phrases move the narrative along at an appropriate pace; the terse writing style perfectly conveys the urgency of Kate Warne’s assignment and the bravery this 19th century heroine had to muster.  The illustrations resemble old-fashioned collage albums (which the illustrator’s note identifies as “scrapbook houses”) and the inclusion of various timely artifacts (such as maps) perfectly support the text.  Nearly every page spread features a small plaque with the date and location of the events therein, helping readers follow along chronologically.  Extensive back matter includes background about Warne, the railroads, and 19th century detective work and will help with any unanswered questions readers may have at the end of the narrative.

Few young readers know the true and dangerous story of the plot to kill the newly-elected President, Abraham Lincoln, before he could take office in 1861. I suspect there are many adults who don't know about it either. Lincoln's inaugural train journey stopped in Baltimore to change tracks and the plotters planned to ambush him there. The fate of the nation hung on the efforts of the Pinkerton Detective Agency and especially on the country's first female detective, Kate Warne!

Beth Anderson's stellar new picture book tells this thrilling tale in a you-are-there, suspenseful style,with cliff-hangar page turns and breathless pacing. She skillfully incorporates an amazing amount of historical information and fascinating details. This is a story fitting for any modern thriller and Anderson tells it with meticulous attention to accuracy and sourcing.

Anderson is greatly aided by illustrator Sally Wern Comport's use of scrapbook-style scenes using period sepia tones. She fills the pages with dramatic scenes, providing historical details, maps, train routes and more.

Back matter is extensive and fascinating on its own.

This is a must purchase, terrific read-aloud for classrooms and has multiple applications. Prepare for kids eagerly demanding more like this and on the topic.

It’s February, 1861 and Abraham Lincoln has just won the election, but the country is deeply divided. Lincoln is set to travel by train from Illinois to Washington, D.C. for the inauguration. But will he make it there alive? It’s up to undercover agent Kate Warne, the nation’s first female detective, and her boss Allan Pinkerton, to foil a plot to kill Lincoln when his train stops in Baltimore. Anderson tells the thrilling, true story masterfully, with spare, gripping prose that makes it impossible not to turn the page. Sally Wern Comport’s gorgeous collage illustrations exude a golden glow. Kids, parents, and teachers will find the story riveting (who ever said history is boring?). Older readers and teachers will appreciate the rich back matter, which tells more about Warne, Lincoln and slavery, and the fascinating way Pinkerton detectives used disguise, deception, codes names, and more, to get their job done.

[Xanthe · Rating 4 out of 5]

An excellent picture book history of a specific crisis point in American history when Abraham Lincoln was targeted for assassination on his train journey to Washington DC even before his inauguration. This book focuses entirely on the role that Pinkerton detective Kate Warne played in this drama and her heroic attempt to warn Lincoln's entourage and get the president-elect to safety. The art in this book uses an antique style that is very cool and interesting and the tight viewpoint on Warne's role gives it tension without bogging it down with details. This book is an interesting comparison to a longer book on the same subject that is clearly meant for older children, Murder on the Baltimore Express which pulls in many more of the players and uncertainties of this whole chain of events. Great snapshot of a crisis that many people today are not aware ever happened and a snappy read for kids.

Beth Anderson is a master at creating books that present history in a way that keeps kids (of all ages) enthralled. In Hiding in Plain Sight, Beth tells the story of Kate Warne, a female detective at the Pinkerton Agency. Kate's assignment is to make sure newly-elected President Lincoln arrives safely on his inaugural train to Washington D.C. Even though most readers know the outcome, the intrigue of Kate's undercover plan to thwart a planned assassination attempt at a stop in Baltimore keeps readers turning the pages! Kate Warne is a strong female character who proudly, albeit anonymously, achieves her goal and sets her place in history as well. The illustrations by Sally Wern Comport offer subdued hues and give a distinct vintage vibe to the story. Excellent back matter is also included.

Packed with suspense and intrigue, Beth Anderson’s telling of Kate Warne’s daring detective work to protect the 16th president is a must-read! This true story about Warne’s undercover work for the Pinkerton Detective Agency and how she setup and shepherded Abraham Lincoln safe arrival from Philadelphia – through Baltimore (the location of a dangerous plot to harm the president-elect) and into the nation’s capital. Stunning art created by Sally Wern Comport transports you back in time to the mid-1800s. Each page turn is a delight packed with tension, thrilling detective work, and terrific illustrations. This lesser known story about Lincoln is a must-read for history buffs, Lincoln fans, and those interested in learning more about this daring young female detective!

I had no idea the Pinkerton Detective Agency had a woman detective on staff at this time and her work is fascinating. While this covers one case in Kate Warne's career, I'm motivated to learn more about her and the work she did in her lifetime. Fascinating historical account I'd never heard of!

I had not known the story of the early Pinkerton work nor of Kate Warne but found this picture book fascinating for the unknown story and the courage and spirit of Kate Warne who probably saved the life of Lincoln as he traveled to Washington to assume the Presidency.
