The Woman on the Orient Express by Lindsay Jayne Ashford
The woman is, of course, Agatha Christie in disguise, trying to escape from situations in life that overwhelm her. Two other women are traveling the same train and both have problems of their own. After the three meet and get to know each other, her disguise is uncovered and the adventure begins.
From the book's blurb: "Agatha isn’t the only passenger on board with secrets. Her cabin mate Katharine Keeling’s first marriage ended in tragedy, propelling her toward a second relationship mired in deceit. Nancy Nelson—newly married but carrying another man’s child—is desperate to conceal the pregnancy and teeters on the brink of utter despair. Each woman hides her past from the others, ferociously guarding her secrets. But as the train bound for the Middle East speeds down the track, the parallel courses of their lives shift to intersect—with lasting repercussions."
This is an interesting book with settings most of us will never visit. Agatha Christy followers will know that Agatha Christie did actually disappear for a time leaving a world of questions and speculations behind her. Her followers will probably read this novel and come away with mixed feelings. I know I did, but still it was an enjoyable read for a lazy weekend.
The book is available at all major book retailers and online.
