@CoolerPseudonym You know Conan Doyle was nearly right about submarine warfare? If Poland hadn't cracked the ENIGMA cypher and sent their notes to the UK where GCHQ followed up and read the U-Boat's orders over Doenitz's shoulder the UK would have been epically fucked during the Battle of the Atlantic in 1940-43. U-boats came much closer to starving the UK into submission than the Luftwaffe ever did by bombing.
Also note: Conan Doyle also wrote SF, eg the Professor Challenger stories.
