This book contains the best detective stories of famous authors. Gal Godfrey is the pseudonym of the Irish writer Charlotte O'Conor Eccles, author of The Devil's Elixir. Having read an advertisement in a newspaper about the sale of the elixir of youth, Augusta Semaphore, an unmarried lady, hastened to take advantage of the offer... Anthony Trollope is an English novelist whose unsurpassed talent lies in a brilliant comic manner of describing everyday events.
