Yet another Hercule Poirot mystery. Something odd is happening at the local youth hostel on HIckory Road. Detective Hercule Poirot finds it "quite interestin." One of its residents is a thief. But no ordinary theirf given the curious items missing: a diamond ring, a tube of lipstick, a stethoscope, and a cookbook. A petty crime? Hardly. In fact this bit of mischief has turned quite deadly. For a murder has now occurred on Hickory Road. The students are afraid. The staff is appalled. And Poirot is wondering...Who's next?
A series of seemingly innocuous items disappear from a student rooming house. Enter Poirot! Beneath this pile or rubble there are several connections that lead the police and Poirot to unravel several murders and to discover a vast smuggling operation. The police fare far better in this one than in most of Aunties mysteries. It also has one of her better plots and sequence of events that leads to the denouement.
