This collection brings together the last cases of Sherlock Holmes and his friend Dr Watson. An old professor starts climbing walls at night. A man dies on a beach, his back covered in red marks, as if he had been whipped. And a mother is caught bending over her baby, with blood on her lips: it is up to Holmes to find the explanation.
Twelve short cases, each with its own puzzle. In two of them, Holmes tells the story himself, something rare in the whole series.
You can read each one in one sitting in the language you are learning.
