A novel from the series about the Belgian detective Hercule Poirot, in which he has to work with the most unusual witness of his career—a dog named Bob.
When Lady Arundell suddenly fell down the stairs in her own house, everyone saw it as an unfortunate accident—after all, she had stepped on a rubber ball left there by her favorite, a fox terrier called Bob. But the more the injured woman thought about it, the more she felt that the fall had been arranged by someone from her relatives. She wrote to the famous detective Hercule Poirot asking him to look into the case.

Poirot cannot bring the unfortunate lady back to life, but he can find the killer. And he will have help from that very dog named Bob…
