A book collector came across a suitcase with rough sketches of Dr. Watson, a friend and colleague of Sherlock Holmes. Fifteen new, unknown to the general public, cases of the legendary detective have finally been published. In these pages, Holmes will have to face drug dealers and people, Mrs. Hudson's double spy, and even a bloodthirsty vampire!

For a long time, the legendary metal suitcase with Dr. Watson's diaries was considered destroyed, but this is not so. John Watson died without leaving a will, and his unpublished notes about the adventures of Sherlock Holmes ended up in the hands of a famous book collector. This unique collection includes 15 new cases of Holmes, in which he outdid himself!
