Sherlock Holmes and Dr Watson are sitting in the parlour at 221b Baker Street. Holmes is doing The Times crossword.
"Here, Watson, you're a medic, what do you think 14 down 'as of, or pertaining to the digestive tract', second letter L, is?"
"Alimentary, my dear Holmes." replies Watson.
"Gad! Of course!" A little while later, Holmes throws the paper down in disgust and starts pacing around the room. "I've got 'em all, Watson, except the last. 'A saffron-hued narrow way between buildings' 1-5-5. The man's a devil and no mistake!" Watson ponders a while before responding.
"A lemon entry, my dear Holmes".
