Lord Darcy. Murders and Magic

The complete edition of the cycle about the genius detective of an alternate Europe "Lord Darcy" in one volume.

What if King Richard the Lionheart did not die in 1199, and his descendants ruled the Anglo-French Empire in the 20th century? 

In the world of Lord Darcy and his assistant, wizard Sean O'Loughlin, the laws of magic complement the laws of physics, but it is the remarkable deductive abilities of the chief investigator Duke of Normandy that allow finding the answer to the question "who is the murderer?"
