A Death in Scilly

No one takes a plane three thousand miles to London, a train three hundred miles to the southwest tip of England, a ship twenty-eight miles to the Isles of Scilly, and yet another boat from St. Mary's to St Agnes, in the hopes of running into a neighbor. Definitely not American, Fiona Smith, who came to the Saltair guest house to hide out from the stepfather she despises and distrusts. But the arrival of Philadelphian Alison Fox isn't the biggest challenge Fiona is facing. A storm has already reached the island when Claire Chapman, the proprietress of the Saltair announces, "There's a body in the polytunnel."
The police can't reach the island until morning, and, with no one able to leave, Fiona and Claire form a team to keep themselves and the Saltair guests safe and to uncover the identity of the murderer before they strike again. Their search will lead them to uncover many more secrets than the identity of the killer
