Sherlock Holmes is one of the most famous detectives in the world and continues to be to this day. However less well known is the fact that author Arthur Conan Doyle implemented the tools of Holmes himself. This documentary looks at Doyle's own case when he took on the case of someone violently attacking horses and cattle at night in a quiet Staffordshire village.
The police get their man but on appeal, Doyle got involved, believing the accused was innocence. Successful from that case, Doyle took on an even more infamous case of the brutal murder of a spinster where a man voluntarily returned from America to stand trial, only to be convicted - incorrectly in Doyle's opinion.
