Once upon a time I had a boyfriend whom I suspected of leading a double life. I took all the goods he had left in my flat and put them in a left-luggage office. I went to meet him as previously agreed, and when I saw him I said "At last, I've found out the truth about you !" He went as white as a sheet and began to dash off, but not before I gave him the left-luggage ticket. Then I watched as he vanished at top speed. I never saw him again, and never did find out the truth, but clearly he had had something dreadful to hide.
