There are echoes of `His Last Bow' in "Sherlock Holmes & the Morphine Gambit" by Jason Cooke. In February 1912 Mycroft Holmes calls on his brother to investigate a burglary at a house on the Norfolk coast, belonging to a German-born businessman and philanthropist, Sir Edward Muster. Relations between Britain and Germany are strained after the previous month's International Opium Convention, at which the Germans urged a ban on the opium trade (which would damage the British economy) and the British demanded a ban on the cocaine trade (which would damage the German economy). The novel is inspired by the story of the Rt Hon Sir Edgar Speyer, who fell victim to anti-German hysteria when war broke out. "The Morphine Gambit" is an exciting story, adequately well-written, though there are a few disconcertingly anachronistic phrases, such as `safe house' and `real ale', and Mr Cooke apparently thinks that the First Lord of the Admiralty is the same as the First Sea Lord. Not so. In February 1912 Winston Churchill, MP held the former post, and Admiral Sir Francis Bridgeman the latter.
