There are also those where a wide variety of topics are mixed and genres. Each such story is a small masterpiece, not inferior to the most famous works of the master. This publication presents selected stories of the writer, collected in a motley, multi-colored mosaic, diverse and, however, giving an excellent idea of the bright talent of Sir Arthur Conan Doyle.
