Re: Sherlock Holmes
There is a bit of sniping lore connected to the Doyle family. Hesketh Prichard (of WWI sniping fame) was a friend of theirs. Prichard was apparently influenced by the Sherlock Holmes stories when he wrote November Joe in 1913, about a First Nation Canadian who employed the science of tracking to solve mysteries.
As an Intelligence officer in WWI, Sir Arthur's son, Kingsley Doyle, ran sniping courses for his unit after attending Prichard's school. Here is an excerpt from a letter from Kingsley to Prichard, as related by Eric Parker:
"... The work of running a brigade course in sniping and observing has kept me pretty close to it, as I was all on my own. ... The General asked me to plan out a course and name the number of men I could take. I had twelve; managed to get a range from 6 to 7 every night; got loophole plates, telescopic sights, and three telescopes, so I was lucky."
