America’s Grand Dame of Mystery: Mary Roberts Rinehart

The butler did it!

Did you know this well-known and often-used phrase traces its’ origin back to a book by American author Mary Roberts Rinehart?

Although not as well-known as Britain’s Agatha Christie is today, Rinehart was a superstar author of the early 20^th century. She captivated readers with suspenseful tales of amateur sleuths solving mysterious crimes.

Literary Achievements

Born Mary Ella Roberts in Allegheny City, Pennsylvania (now part of Pittsburgh) on August 12, 1876, Rinehart did not begin her career as a novelist. She trained as a nurse and married physician Stanley Rinehart in 1896. When financial setbacks struck the family, she turned to writing as a way to supplement their income.

Rinehart's breakthrough came with The Circular Staircase in 1908, a novel that became a bestseller and established her as a major force in mystery fiction. The book sold more than a million copies and helped define the modern mystery novel.

It introduced what critics later called the "Had-I-But-Known" style of storytelling, in which a narrator looks back on events and hints that disaster might have been avoided if only certain clues had been recognized sooner. This technique became one of Rinehart's trademarks and influenced generations of suspense writers.

Over the course of her career, Rinehart wrote more than 60 books, along with hundreds of short stories, articles, poems, and plays. Her works ranged from mysteries and suspense novels to humor and adventure stories. She also created several memorable recurring characters, including the nurse-detective Hilda Adams, often called "Miss Pinkerton," and the irrepressible Letitia "Tish" Carberry.

One thing I find so interesting about her is that Rinehart's interests extended well beyond fiction. During World War I, she worked as a war correspondent, reporting from the front lines in Belgium for The Saturday Evening Post. At a time when few women were given such opportunities, she interviewed political and military leaders and brought firsthand accounts of the war to American readers.

Success Beyond Measure

Her popularity was astonishing. For decades, she was one of America's best-selling authors, and some sources describe her as the highest-paid writer in the United States during much of the first half of the twentieth century. By the time of her death in 1958, her books had sold more than 10 million copies worldwide, and her stories had been adapted into numerous films, plays, and radio productions.

Although her name is less familiar to modern readers, Rinehart's influence on the mystery genre remains significant. She helped shape the structure of the modern suspense novel, popularized female amateur detectives, and demonstrated that mysteries could blend humor, romance, and psychological tension. Many of the conventions readers now associate with cozy mysteries and romantic suspense can be traced back to her pioneering work.

Today, Mary Roberts Rinehart deserves to be remembered not only as a bestselling author but as one of the architects of modern mystery fiction. Her stories entertained millions of readers, and her innovations continue to echo through the genre more than a century after she first picked up her pen.

The Best of Mary Roberts Rinehart

If you’d like to get to know Rinehart’s work, consider reading one of these four novels. I took a poll among her fans, and these are generally viewed as her best murder mysteries:

The Circular Staircase (1908)

Rachel Innes rents a country mansion for the summer, hoping for a peaceful retreat. Instead, mysterious footsteps, strange disappearances, and a shocking murder plunge her into a tangled mystery involving hidden identities, family secrets, and a notorious circular staircase at the center of the intrigue.

The Man in Lower Ten (1909)

Lawrence Blakeley boards a train for what should be a routine business trip, but awakens to discover that another passenger has been murdered and his own identity has been mistaken for the victim's. As he races to clear his name, Blakeley becomes entangled in a fast-moving mystery filled with theft, deception, and unexpected romance.

The Door (1930)

When a wealthy family's dinner party ends with a guest mysteriously shot in a locked room, suspicion falls on everyone present. As the investigation unfolds, hidden motives and long-buried secrets emerge, revealing that the answer may lie behind a seemingly ordinary door.

The Wall (1938)

A quiet household is thrown into turmoil when a murder exposes tensions, betrayals, and secrets hidden within the family. As suspicion mounts, the investigation uncovers a figurative "wall" of deception separating appearances from the truth, leading to a surprising and dramatic solution.

The Wall could easily fit on my list of seaside mysteries. Could one of these cozies be your next
