Frank receives by smart phone £5,000 anonymously to solve a crime yet to be committed on a walk along Shakespeare's Way organised by Swift Feet Walks. On the tour with Frank are Ben Yang and his wife Chen, a neuro-surgeon, Summer Styles a prison physiotherapist, and Beverley Sinclair who was an old friend of organiser Julian Hope. During the first night Ben Yang is murdered and Sergeant Keeler arrests Frank on the evidence he has. Luella and Sebastian search for a link and all the tour party had won the trip as a prize including Frank who hadn't opened his emails. They then discover Michael Reynolds, a thief who was married to Sinclair and business partner with Hope and he had fallen from a roof escaping from Frank leaving him paralysed. Released from prison early on compassionate grounds he died within days from complications with his injuries.
