Read it through once

In Paris we often saw in shop windows the sign “English Spoken Here,” just as one sees in the windows at home the sign “Ici on parle francaise.” We always invaded these places at once--and invariably received the information, framed in faultless French, that the clerk who did the English for the establishment had just gone to dinner and would be back in an hour--would Monsieur buy something? We wondered why those parties happened to take their dinners at such erratic and extraordinary hours, for we never called at a time when an exemplary Christian would be in the least likely to be abroad on such an errand. The truth was, it was a base fraud--a snare to trap the unwary--chaff to catch fledglings with. They had no English-murdering clerk. They trusted to the sign to inveigle foreigners into their lairs, and trusted to their own blandishments to keep them there till they bought something.
