THE IMPATIENT DISSIDENTS. The Czar of Russia was assassinated in March 1881. That summer an attempt was made to murder his daughter while she was riding through Kensington Gardens with her husband, the Duke of Edinburgh. A Russian Count has been found dead in a hospital in London. Scotland Yard, the Home Office, and Mycroft Holmes arrive at 221B to enlist the help of England's only consulting detective to catch the assassin before he can strike again. But will Sherlock Holmes succeed? And what unique strategy will he contrive to trap his prey? This new mystery is a tribute to The Resident Patient.
