Twenty-three and a half hours' leave

In Short

Mary Roberts Rinehart’s lighthearted 1918 novella captures the reckless optimism of American doughboys preparing to ship off to the Western Front. When an unlucky inspection leaves Sergeant Gray stripped of his regulation uniform right as his long-awaited twenty-three and a half hours’ leave begins, his desperate search for civilian clothes hurls him into a slapstick misadventure. He tangles with a suspicious city photographer, catches the eye of the general’s spirited niece, and tries to win a foolish bet. Grounded in authentic camp slang, the story remains an affectionate, fast-moving artifact of Home Front morale.

The Story

On the eve of embarking for France in 1918, the cavalrymen of the Headquarters Troop are exhausted by endless paperwork, inspections, and drill. Sergeant Gray, nursing a bruised heart after the girl back home marries another man, makes a rash bet with his mess sergeant and stable sergeant: he wagers that within a week he will eat a bran muffin at breakfast with their intimidating commanding general.

The troop moves by rail to an eastern port of embarkation, where leave is finally granted. Determined to impress anyone he meets, Gray puts on a custom-tailored, non-issue uniform. His vanity backfires when a strict camp inspector discovers his rule-breaking attire and orders his non-regulation clothes confiscated and burned. Before the supply sergeant can bring replacement khaki breeches, the sergeant is arrested for an unrelated infraction. The troop is left stranded in their barracks clad only in slickers and underwear, but Gray refuses to forfeit his twenty-three and a half hours of freedom.

Wrapped in a yellow raincoat, Gray sneaks out of camp and meets Peggy, a practical young woman driving soldiers to the streetcar line in her small car. Peggy suspects that a local photographer named Mr. Booth, who claims to be from Vienna, is actually gathering military intelligence from departing soldiers under the guise of taking portrait photos. She enlists Gray to help her investigate.

When Gray visits Booth’s studio, he drops misleading hints about faulty weapons and delayed troop sailings to test the man. However, his fellow soldiers track him down to retrieve the borrowed slicker for the rest of the troop, stripping Gray down to his underwear in the building's hallway. Desperate to hide, Gray flees into Booth's studio, wraps himself in a decorative Indian blanket, and discovers Booth and an accomplice handling suspicious photographs. Using his fists, Gray overpowers both men, ties them up, and dons a civilian cutaway coat before the police arrive.

The police initially throw Gray into a cell for brawling without clothes, but Peggy alerts her uncle—who happens to be Gray's general. amused and impressed by the sergeant's resourcefulness in exposing a spy ring, the general pulls Gray from the station house and treats him and Peggy to a late breakfast at a high-end restaurant, complete with bran muffins. Gray wins his wager, captures Peggy’s heart, and cheerfully accepts a final arrest by the military police for being out of uniform, ready to ship out to war.

How It Unfolds

Camp routines and a wild wager Sergeant Gray writes up his own disciplinary report for being absent without leave while complaining about military routine to the mess sergeant. To break the monotony, he bets his squadmates that he will secure an invitation to eat breakfast with the troop's formidable general.

The journey to the coast The troop entrains for the port of embarkation, passing the time by playing pranks, singing, and mocking their leaders. Along the way, word of Gray's impossible bet filters up to the general himself, who dismisses it as absurd while eating his morning muffin.

Stripped of authority and attire At the embarkation camp, Gray puts on a high-end tailored uniform to celebrate his upcoming leave. A rigid camp inspector catches the infraction, confiscates the custom suit, and leaves Gray and his men stuck in their quarters wearing nothing but issue slickers when the supply sergeant is suddenly arrested.

A chance encounter in a small car Clad only in a raincoat, Gray slips out of camp and gets a ride from Peggy, a general's niece who uses her automobile to transport soldiers. She warns him about local spies targeting troops for secret departure dates and asks for his help uncovering a suspicious photographer.

Brawling in the dark Gray visits the photographer's studio to feed him fake military gossip, but his own squadmates corner him in the hallway to reclaim their slicker. Stripped once again, Gray wraps himself in an Indian blanket, catches the photographer red-handed in espionage, and subdues two men in a chaotic fistfight.

Muffins with the commander After a brief stint in a police cell, Gray is rescued by the general and Peggy. Over a victory breakfast of bran muffins at a fine city restaurant, Gray wins his bet, earns Peggy's admiration, and marches off to join his unit for France.

The People

• Sergeant Gray: A tall, irrepressible cavalryman with a penchant for drawing faces on his fingernails and getting into minor trouble. He wants to prove his worth after being jilted by his sweetheart, regain his freedom on leave, and win his absurd bet; despite losing his clothes repeatedly, his physical courage and quick wits earn him a general's respect and a new romance.
• Peggy: A sharp, patriotic young woman who drives her personal car around camp to transport soldiers in memory of her brother serving in France. She wants to catch enemy spies operating near the port and keep young enlistees from leaking troop movements; her sharp observation skills drive the unraveling of the espionage plot.
• The General: An aloof, highly disciplined commander feared by his men, referred to affectionately and nervously as "the Old Man." He wants strict order across his division as they prepare for overseas deployment, but his hidden sense of humor leads him to reward Gray's chaotic initiative.
• Mr. Booth: A court photographer formerly of Vienna operating near the military transit hub. He seeks to gather intelligence regarding American transport schedules and weaponry from naive soldiers, but he ends up bound in his own studio after underestimating Sergeant Gray.

In Its Own Voice

“Did you ever think,” reflected Sergeant Gray, leaning back in his chair and tastefully drawing a girl’s face on his left thumb-nail, “that the time would come when you’d be planning bran muffins for the Old Man’s breakfast? What’s a bran muffin, anyhow?”

The opening banter captures the absurd shift from civilian life to military routine as Gray hatches his impossible wager over late-night paperwork.

“Might as well get used to it, old son,” said Sergeant Gray, and hummed a little ditty to the effect that “They are wild, simply wild, over me.”

Gray maintains his breezy bravado even when facing dirty barracks and the uncomfortable realities of field soldiering.

In his eyes there was suddenly that curious blend of hope and sadness which shines from the faces of those who love and, loving, must go away to war.

The story closes on a touch of quiet depth as the comedy yields to the sobering reality of deployment.

What It's Really About

Behind its light slapstick structure, the story explores the tension between military regimentation and American individuality. Sergeant Gray represents the citizen-soldier who respects authority only up to a point, retaining his sense of humor, personal vanity, and romantic optimism under the eye of strict discipline. The plot relies heavily on the frantic atmosphere of World War I mobilization, where rumors, official secrecy, and home-front security created a heightened sense of urgency. Rinehart highlights how shared sacrifice and small acts of kindness connect civilians and enlistees, using the absurd sequence of lost uniforms and spy-hunting to show that youthful resilience thrives even on the brink of shipping out to a dangerous front.
