'An Unfortunate Return' is the 27th novel in the Pitkirtly Mysteries series.
The small town of Pitkirtly is infested with roadworks thanks to the local council's plan to introduce a Low Traffic Neighbourhood. Many local people predict traffic mayhem, but none of them expect a murder, a mysterious attack in broad daylight outside the church hall, or the more minor havoc wreaked by an environmental campaigner. Several of these incidents seem to be connected to a disappearance in the Alps a few years before. Local knowledge, sticky notes and a good deal of thought are required to solve all the puzzles.
