Robust, well-plotted, original mysteries. Holmes felt somewhat blander than the original but he and Watson are generally true to form.
What lost a star are words and phrases that I believe are anachronistic or Americanisms: coffee table, clueless, lowest of the low, crime-fighting. And all the Christmas decorations! “Much to the chagrin of my roommate, Sherlock Holmes, Mrs. Hudson had festooned 221B Baker Street with holly, garlands and a large wreath on the door.” Much to my chagrin as well—they jarringly disturb the flow and atmosphere of the stories.
Still worth reading of you want some clever pastiches with unusual plots.
