‘R.J. Decker’ and ‘Young Sherlock’ offer distinctive tales of the prisoner-to-PI pipeline

Two new TV series are starting this week. “R.J. Decker” is a typical example of its kind, created with the style of Carl Hiaasen. The other, “Young Sherlock,” is based on the stories of Arthur Conan Doyle and expanded upon in novels by Andrew Lane. It shows a 19-year-old Sherlock Holmes, so it’s not a traditional detective show, but it explores the origins of the character who would become the famous detective.
