The Rest Hollow Mystery

Kenwick himself had no recollection of the accident. But he knew that there must have been one, for when he recovered consciousness, his clothes were full of burrs, his hat was badly crushed, and there was a violent throbbing in one of his legs.
With both hands gripping the aching thigh in a futile effort to soothe its pain, he dragged himself into the clearing and looked about.
