The Forest Road runs west from St Martin's across the high middle of southern Guernsey towards the Forest church at Le Bourg. In the nineteenth century it was a long walk between farms, with no lighting and high hedges. The man in this story was going home to his house near the church when he realised something was behind him: a black dog, dragging chains that clanked on the road.
Carey gives no name and no date, only that the woman who told the story was the dead man's daughter. He did not fight the beast or speak to it. He got home, took to his bed from the shock, and died "very shortly afterwards". The chained black dog is the same type as the Bête de la Tour in St Peter Port, and the idea that meeting one is fatal runs through the Guernsey accounts, from Le Chien Bôdu in the Vale to the Rue de la Bête at L'Erée.
Visit Guernsey's folklore article gives the story a slightly different shape, placing the dog at Le Bourg and having the man die the next day. That fits the original closely enough to be the same tradition. The map marks Le Bourg, at the Forest end of the road.
