Yes, yes, Murder on the Orient Express is much more known and beloved. But although the train is famous, it spends most of the book stuck in a snowdrift, which I found very disappointing. This charming outing for Miss Marple starts when her friend sees a murder from one train while travelling in another. There’s very little blood or violence in this book, but all the excellent plotting you’d expect from Christie is here, twisting a railway murder into a classic country house mystery, with two boys on their school holiday helping hunt for clues. A good introduction to the queen of crime for a young reader.
