DI Byron Unsworths working holiday on a heritage railway in Wales is rudely interrupted by the discovery of a corpse on the train he was responsible for. It shouldnt be his problem except that the North Wales Police Force is stretched to breaking point with widespread civil unrest. It is a clear case of suicide would he wrap up the case for them? No one, least of all Detective Inspector Unsworth, could have foreseen the potentially catastrophic outcome that the death in the last carriage would produce. A pacey detective thriller which gives centre stage to the most enduring and authentic player the vibrant Ffestiniog Railway.
