In the mid-eighteenth century, Sir Gerald Sandford is building a new hall and a replacement water mill in Flemish brick while trying to introduce a hardy breed of Welsh cattle onto the heathland on his estate but strange behaviours are being exhibited. By 1942, the heathland near Sandford is serving as an airfield for newly arriving American bombers and given the rigours of aerial missions across Europe, it's unsurprising that some aircrew are suffering from both over-reliance on alcohol and PTSD. Or are they? In the present day, houses built on the former airfield have been abandoned amid speculation that their occupiers have unusually high incidences of illness and premature death, not to mention psychiatric conditions. insurance investigator, Robbie MacFarlane, and his girlfriend Sally Miller are ideally placed to try to discover the truth, house-sitting as they are for Robbie's father at Sandford Mill only minutes away from the affected homes. Can they solve the Sandford mystery?
