An unsolvable crime

When Miss Marple receives a letter from the recently deceased millionaire Jason Rafiel, she’s not sure what to make of it. Knowing her deductive skills, he challenges her to solve a crime. If she does so, she will inherit £20,000.

The only problem is that he has failed to mention who was involved, or where, and when the crime was committed. Jane Marple is intrigued.

Never underestimate Miss Marple.
