To understand the strange goings on at The Pale Horse Inn, Mark Easterbrook knew he had to begin at the beginning. But where exactly was the beginning? Was it the savage blow to the back of Father Gorman's head? Or was it when the priest's assailant searched him so roughly he tore the clergyman's cassock?

In utter disbelief, Miss Marple read the letter addressed to her from the recently deceased Mr. Rafiel...an acquaintance she had met briefly on her travels. He had left instructions for her to investigate a crime after his death. The only problem was, he had failed to tell her who was involved or where and when the crime had been committed.
