``Then what is it?'' he said. ``Can you tell me?''

``Don't worry,'' she said, ``it's nothing bad at all. Just unusual. Very very unusual.''

She touched his hand, and then leant forward and kissed him briefly.

``I shall be very interested to know,'' she said, ``if you manage to work out what it is this evening.''
