The book, written in the 19 c. by British journalist and author of mystery and horror fiction J. E. Preston Muddock. For a time his detective stories were as popular as those of Arthur Conan Doyle. It is about a married gentleman, first accused of murder of his lover and later acquitted due to brilliant investigation by police in spite of alleged heavy evidence against the gentleman. The real murder, ex-husband of the victim, is pretty evident to the reader.
