Bridges Down--Roads Impassable--Killer Trapped April in Florida and Benedicta (Ben) O'Keeffe is enjoying balmy temperatures during the last few days of a six month stint with a US law firm. A week later, she returns to Glendara, Inishowen, where a charity cycle event is taking place. The town is abuzz with excitement, but it starts to rain, causing the cyclists to postpone the start of their event and stay overnight in the town. The rain doesn't stop--it becomes relentless, torrential. In the middle of the night, Police Sergeant Tom Molloy is called out to Mamore Gap, where a body, dislodged from a high bank by the heavy rain, has fallen onto a passing vehicle. It is identified as Bob Jameson, a well-known charities boss and the organizer of the cycling event. Stunned, the local doctor finds evidence of a recent snakebite. Terrible weather persists and soon bridges are down and roads are impassable. Glendara is completely cut off and since there are no native snakes in Ireland, could there be a killer trapped in the community? With no help from the outside world, it's left to Molloy--with Ben's assistance--to find out who is responsible for Bob Jameson's bizarre death.
