The Crystal Cavern – by Hannah Alexander (2003)

The Crystal Cavern

If you’re in the mood for a good who-dunnit mystery, this is an excellent choice. Sable Chamberlain, a small-town doctor, and a paramedic, Paul Murphy, are looking into the recent death of her grandfather. While they are trying to find out what happened, they are framed for his murder and end up fleeing town on a cross-country bus.

An ice-storm hits, and Jerri, the bus driver, struggles to keep the vehicle on the road. Conditions worsen, and they can’t keep going. Fortunately, they are within walking distance of Sable’s childhood home, so the seven people aboard abandon the bus and hike to the house. There they discover that Craig, a longtime neighbor, is taking care of the house. The electricity is out, but there is a wood-burning stove for heat and cooking.

This is no ordinary house. The basement has an entrance to underground caves with stalactites and stalagmites. Sable and Craig have explored the caves as children, and know them like the back of their hands. The rest of the group see the caves as dangerous. They are trapped in the country house for days as they wait out the storm. Weird things start happening, and it becomes obvious that one of them is a killer – but who is it?
