This is the 21st in the Hillary Greene mystery series. I have read about half of them. This book would work as a standalone.

Former DI Hillary Greene, now retired, has been hired by Thames Valley police as a consultant for cold cases. She lives on a narrowboat and drives a car she has tagged, “Puff the Tragic Wagon”, which gives you some insight into her character!
Hillary has also written a mystery book which is about to be published. To help promote it, she takes a holiday trip to a quaint town in Wales that is known for its bookstores. While staying at a charming inn, she embarks with six fellow guests on a nostalgic and picturesque steam train trip. When one of the group is murdered while sitting on the train, Hillary becomes involved in the investigation.

This is an Agatha Christiesque locked room mystery which the author acknowledges through Hillary’s narrative. Faith Martin writes absorbing British police procedurals and this one is no exception. The story is engrossing and entertaining with good character development. Hillary is a strong, capable individual and I really enjoy the humor expressed in Martin’s writing.

I recommend this series for fans of British police procedurals with an engaging protagonist.

This was my first DI Hilary Greene, read, but I very much enjoyed it. I don't think I missed anything from the previous books. I really enjoyed how Hilary worked with Officer Jones. The story wasn't unique, but it did feel refreshing, which was nice. And like with any other murder mystery book, I didn't see it coming who the killer was.

Thank you, NetGalley, Joffee Books, and Faith Martin, for this early copy. All opinions are my own.

This was giving Agatha Christie. I loved it! The pacing was well done and the characters actually had personality, which can be hard to find sometimes. I would recommend this to anyone that likes murder mysteries

Former Detective Hillary Greene is off on holiday. For a blissful two weeks, her life will be free of murder victims, murder suspects, and, best of all, no paperwork. She’s heading for the beautiful Welsh town of Hay-on-Wye, where she plans to spend her time browsing old bookshops and generally relaxing. Hillary arrives at the picturesque Riverside Inn where she finds the residents an eclectic bunch: a charming Irishman, a rich American and his spoilt daughter, a thrice-married Canadian influencer, a wealthy widow and a taciturn taxidermist. The next day, Hillary and her fellow guests set off on a steam train ride through the stunning Cambrian Mountains. But when the train arrives at its final destination, not all the passengers get off. One of them has been stabbed neatly and cleanly through the heart! Good book! This book had suspense, intrigue, action, murder, mystery, a fantastic who done it and some crazy twists and turns! The storyline was very interesting and kept me glued to my kindle! I definitely recommend reading this book! Thank you NetGalley and the publisher for sharing this book with me!

Thanks to NeGalley and Joffe Books for the opportunity to read Murder on the Train by Faith Martin. So fun to spend time with Former Detective Hillary Greene again!
