‘You’re wasted in OCAL, Tad. You should come to us.’

But Tad was not listening. ‘You’ve no idea what a queer feeling it was to see Bill’s writing suddenly like that, among all those strange names. It sort of stopped my breath.’

Grant took Lloyd’s picture of the crater ‘ruins’ from his desk and brought it over to the table. ‘That is what Heron Lloyd thinks that Bill saw.’

Tad looked at it with interest. ‘It sure is queer, isn’t it? Just like ruined sky-scrapers. You know, until I saw Arabia I thought the United States invented sky-scrapers. But some of those old Arab towns are just the Empire State on a smaller scale. But you say it couldn’t have been this that Bill saw.’

‘No. From the air it must be quite obvious what it is.’

‘Did you tell Lloyd that?’

‘No. I just let him talk.’

‘Why do you dislike the guy so much?’

‘I didn’t say that I disliked him.’

‘You don’t have to.’
