‘Room number?’

‘Forty-four.’

‘Good. You see, it is only during my working hours that they have their spies with me. How long will you stay?’

‘Till Friday,’ I answered.

I thrust my leg out for him to see.

‘So you lose a leg, eh?’ He clicked his tongue sympathetically. ‘Above the knee?’

I nodded.
