After surviving an attempt on his life in Paris, Sherlock Holmes returns to London, where the great detective is almost immediately enlisted by his brother to secure the safety of the delegates at a top-secret peace conference. With Europe a veritable powder keg in the years before World War I, Holmes understands any misstep on his part could prove fatal and possibly plunge the continent into war. However, after pledging to do his utmost for "King and Country", Holmes suddenly finds himself overwhelmed by an onslaught of cases.

January 1888: Dr. John H. Watson has returned to 221b Baker Street, just weeks after a personal tragedy has left him bereaved and bereft. Feeling like a broken man, his plans and dreams lying in ruin, he slowly tries to make his way forward, with the help of Sherlock Holmes and Mrs. Hudson. Unexpectedly, he finds himself standing in the path of a madman—who suddenly and irrationally blames Watson for his apparent defeat.
