Q: Take the name 'Boris Karloff.' It contains the letters of 'Oslo' in left-to-right order (although not consecutively). Now write down these three names: Leonardo da Vinci, Frank Sinatra, Stephen Douglas. Each conceals the name of another world capital in left-to-right order, although not in consecutive letters. What capitals are these?I wasn't able to post the puzzle earlier because I had just pulled an all-nighter. We had intended to get to bed at an hour that was reasonable. However, since we needed to construct our Halloween costumes in time for the parade today, we couldn't settle for inaction.
Edit: Three airport codes are hidden in the last word of each sentence (alL-nigHteR=LHR, rEaSonaBle=ESB, InaCtioN=ICN). Doesn't really help you solve the puzzle, but it might have confirmed you had the right locations.
A: LONDON (England), ANKARA (Turkey), SEOUL (South Korea)
