Van Dine, S.S.: Vance 01 - The Benson Murder Case. v1. 10 Sep 07
The first in a series of detective stories by "S.S. Van Dine", the pen name of Willard Huntington Wright, an American author and script writer. The series features the amateur investigator "Philo Vance", and are all detective stories of the "old school", complete with plans of the murder scene, solving of clues, questioning of witnesses, and so forth. An excellent read.
I'm planning to do the entire series, but it may take me a while. I'm going to do them as separate books, rather than anthologies, simply because preparing each book takes a great deal of work - they have lots of diagrams, footnotes, and so forth. I'll label them with the position in the series, as in this case "Vance 01 - The Benson Murder Case". (All the books are called "The <something> Murder Case").
This first book in the series, "The Benson Murder Case", sees Philo Vance investigating the murder of Alvin Benson, found dead in an armchair in his living room with a single bullet wound to the head.
