The repulsive story of the red leech and others

I see my notes upon the repulsive story of the red leech and the terrible death of Crosby, the banker. Here also I find an account of the Addleton tragedy, and the singular contents of the ancient British barrow. The famous Smith-Mortimer succession case comes also within this period, and so does the tracking and arrest of Huret, the Boulevard assassin — an exploit which won for Holmes an autograph letter of thanks from the French President and the Order of the Legion of Honour.
