Pascoe listened. At the head of the foyer were six lifts, seemingly in constant use even at this hour. They announced their arrival with a melodic ping! The pings were pitched at slightly different levels and as Pascoe listened their interval and sequence suggested the communications code from Close Encounters. At last! he thought. An explanation of why hospitals always give the impression of being run by aliens disguised as human beings.

'See the pay-phone over there?' said Headingley. 'All the time Ruddlesdin was talking I could hear those bloody pings! The bastard was here!'

'So what?' said Pascoe. 'He came round here to check on Deeks. Sergeant Wield told me.'

'Mebbe. But he must have got here not long after I'd got Mr Dalziel out of the place. Christ knows what that daft doctor said to him.'

'But what could Sowden tell him?' asked Pascoe. 'That he thought the old fellow said something about the driver being pissed before he died? What's that mean? Anyway, why should Sowden get himself involved in something so vague?'

'Christ knows,' said Headingley. 'He seemed to have managed to work up a fair head of steam for some reason. Even when Charlesworth said he was the driver, this didn't calm him down. Not that I didn't have some sympathy with him. Bloody Charlesworth just stood there, puffing out cigar smoke, a bit of a sneer on his face like he was saying, That's my story. Prove different.'

'George,' said Pascoe quietly. 'You don't think there could be anything different to prove, do you?'

Headingley shook his head.

'No. No. Not Andy, it's not his style. Mind you, Peter, he was as drunk as I've seen him, no doubt about that. I always thought he was unsinkable, but by Christ he'd hit an iceberg tonight. I've as good as locked him in his office and I told the lads on the exchange that no calls were to be put through to him.'
