Witches are dangerous. They can kill you with a look, or a word. They can send their friend the Devil after you in the shape of a dog or a cat. They can make a clay picture of you, then break it.... and a few weeks later, you are dead. Today, of course, most people don’t believe in witches. But in 1612, everybody was afraid of them. Young Jennet Device in Lancashire knew a lot about them because she lived with the Witches of Pendle. They were her family.

In a house in Oxford, three people are having breakfast: Carol, her husband Jan, and his father Josef. They are talking about Prague, because Carol wants them all to go there for Christmas.

He still remembers another Christmas in Prague, many long years ago - a Christmas that changed his life forever.

Adapted from the stories by Arthur Conan Doyle.... Sherlock Holmes is the greatest detective of them all. He sits in his room, and smokes his pipe. He listens, and watches, and thinks. He listens to the steps coming up the stairs; he watches the door opening – and he knows what question the stranger will ask.

In these three of his best stories, Holmes has three visitors to the famous flat in Baker Street – visitors who bring their troubles to the only man in the world who can help them.
