When Boston librarian Iris Quinn turns 50, the reality of her safe, staid life suddenly becomes unbearable. She's never done anything spontaneous. Throwing all caution to the wind, she decides to make a long-held dream of hers come true. She drains her savings account to purchase a ticket for a luxury train ride from London to Istanbul aboard the famed Orient Express. Although Iris feels too plain and ordinary to be embarking on such a glamorous adventure, she's also utterly entranced. Feeling as if she's stepped inside an Agatha Christie novel, she vows to embrace the experience for all its worth. Just as she's starting to really enjoy herself, however, a passenger is killed—and a shrewd Swiss detective pegs Iris not only as a suspicious outsider but also as the prime suspect in the murder. Desperate to clear her name, she vows to use her keen observation skills to unmask the real killer. Can she solve the case before anyone else dies? Or will she become the murderer's next victim?

No One Sleeps on the Orient Express by Irene Hagan is the first installment in a promising new cozy mystery series. As a 50-year-old book lover myself, I found Iris to be a kindred spirit. She's down-to-earth, relatable, compassionate, and clever. Her habit of sorting everyone she meets into certain stereotypes from various literary genres made me laugh. I especially liked seeing how those people smashed through those tropes, teaching the shelted Iris that real people are much more complex than book characters. As for the other passengers on the Orient Express, there isn't time to get to know any of them very well. I would have liked to delve deeper into their backstories. In fact, No One Sleeps on the Orient Express may be the first cozy mystery I've ever read in which I wanted the book to be longer than it was. (It's only 249 pages.) The murderer's identity is a little too obvious; a more intricate plot with twists and red herrings (á la Ms. Christie) would have served the story well, I think. Nevertheless, I very much enjoyed No One Sleeps on the Orient Express. The novel is atmospheric, funny, entertaining, and clean. I was thrilled to discover that the next installment, It Always Rains at Ashford Castle, comes out in September because I really can't wait to see what Iris gets up to next.
