Phantom Detective (C. S. Montanye, Paul Ernst, Donald Keyhoe, etc).
The collection is broken down and arranged chronologically: The Victorians, Nineteenth-Century Americans, The Edwardians, Early Twentieth-Century Americans, Between The World Wars, The Pulp Era, Post-World War II, and The Moderns. Each of the stories has a short introduction including publication notes and author bios. The intros were a real treat to read and even though I love detective fiction trivia, there was quite a lot that was new to me.
I love anthologies and collections, and this one is no exception. The hook for the anthology is that the stories feature one or more rogues/villains. Sometimes they're portrayed in a more favorable light, like the stories featuring Lupin and Raffles and some are just dastardly, Dracula and Horace Dorrington, for example.
Since the book covers such a broad span of time, some of the stories reflect the language and dialogue of their period, but for anyone comfortable reading a Holmes story, these stories won't present any problems at all.
I enjoyed quite a lot of these and even enjoyed reading a few of them aloud together (fun road trip activity, passenger reads, driver drives :).
Heartily recommend this collection. I found a number of authors who were not previously familiar to me for further reading.
The anthology's editor, Otto Penzler, has curated another superbly entertaining thematic collection.
Disclosure: I received an ARC at no cost from the author/publisher.
