From New Scientist #1309, 10th June 1982 [link]
Four typical solvers of the Enigma live at the four corners of an imaginary square. They all live very happily knee deep in calculators, log tables, string, sticky tape and aspirins, emerging just occasionally to go to work. By trade they are an astronomer, bus driver, cryptographer and dustman. Here are five statements about them, just one of which is false:
(1) Paul lives one mile due NW of the astronomer;
(2) Quentin lives one mile due NE of the bus driver;
(3) Randolph lives one mile due SW of the cryptographer;
(4) Sebastian lives one mile due SE of the dustman;
(5) Randolph lives due S of the dustman.
Find which solver lives in which corner, and what each of their jobs are.
There are now 594 Enigma puzzles on the site, with a complete archive of puzzles from the start of Enigma in February 1979 up to this puzzle, originally set in June 1982 (164 puzzles). And also a complete archive of puzzles from August 2005 to the final Enigma puzzle in December 2013 (428 puzzles).
Numerically this is just over one third of the 1780 Enigma puzzles ever published. Sometimes (at Christmas) there have been multiple puzzles with the same number, so in total I expect there are slightly more than 1780 Enigmas – although there have been a couple of puzzles that have been published more than once as different Enigmas, so that brings the total back down again. Whatever the final tally is I’m choosing to celebrate the fact that I’m one third of the way towards a full archive of all Enigma puzzles now.
I shall keep adding puzzles to the site as time permits. Enjoy!
