For fans of The Thursday Murder Club, The Maid, and How to Solve Your Own Murder

Librarian Iris Quinn has spent fifty years perfecting the art of playing it safe-until her milestone birthday arrives with nothing but grocery-store cake and the realization that "someday" has quietly become "never."

In a rare moment of recklessness, she cashes out her emergency fund and books a first-class ticket on the legendary Venice Simplon-Orient Express, expecting velvet seats, vintage champagne, and perhaps a little clarity.

Instead, she finds herself trapped on a luxury train with a dead passenger, a poisoned champagne flute, and a carriage full of wealthy travelers who each seem to be lying about something. When the onboard detective decides Iris is his prime suspect, she must rely on the skills no one ever notices-cataloging details, cross-referencing stories, and spotting what doesn't belong-to unravel a tangle of forged identities, bitter feuds, and elegantly constructed lies.

To clear her name, Iris will have to solve a murder, outsmart a train full of suspects, and discover who she's willing to become when the careful life she's spent decades building finally jumps the tracks.

Warm, witty, and deliciously twisty, No One Sleeps on the Orient Express launches The Murder, She Booked Series-intelligent mysteries for anyone who's ever wondered if their best chapters are still ahead, and decided it's time to find out.
