'It's not, you see, just a case of someone — anyone — "looking after" this important Soviet contact in Moscow. Since the rendezvous with the executive in Bucharest was set up, a great deal of raw intelligence has been coming in for analysis, and I should tell you that if we'd known as much as we do now about Zymyanin, we wouldn't have left it to a minor cell to find out what information he has for us. We would have asked him to make the contact in Moscow, not Bucharest, and we would have sent in someone of very high calibre to meet him.' One of the windows vibrated as a truck rumbled past the hotel, and I watched its brake lights come on at the intersection. 'We would like,' Croder said, 'to do that now.'

I said, 'I hope it all goes well.'

This man was pussyfooting me into going out again, putting his cold steel claw into a velvet glove and stroking me with it.'

The lights went green and the truck pulled away through the intersection, a big round cabbage dropping onto the street and rolling into the gutter. It looked sickeningly like a head.

'I'm still on leave,' I told Croder. We always played this game and he always won, but I still put up a bit of protest because there was usually something I could get out of him in exchange. This time I had something important.

'I am aware of that,' he said, 'and of course I apologize.'

You don't take an apology lightly from Chief of Signals. It's like God apologizing for the Flood.

I watched the woman at the opera house, Valeria Lagorio, one pale ivory arm resting on the crimson plush of the loge, her huge eyes intent on the stage. Then the picture faded as I said, 'I'll do a trade with you.'
