It usually turns out that the events were performed by all too human perpetrators, although occasionally a supernatural element remains unexplained. In the case of the Black Dog, a small black dog suddenly appears out of where and then disappears. According to the legend, whoever sees the dog three times, dies. When a Wall Street financier, who is about to come under indictment for embezzlement, sees the dog three times and then falls off a cliff, Marcie is quickly on the case. She soon finds that many of the man's acquaintances are happy to see the victim dead, and it soon becomes obvious to Marcie that determining if he died due to human agency or the curse of the Black Dog will t be easy.
