Thief of Time - Lifetimer summon

'I know. I had to. There was no other way. Can you find Lu-Tze? I know Death can locate any living
thing, and since you-'

'All right, all right, I know,' said Susan darkly. She held out her hand and concentrated. An image of
Lu-Tze's extremely heavy lifetimer appeared, and gathered weight. 'He's only a few hundred yards over there,' she said, pointing to a frozen drift.

'And I know when he is,' said Lobsang. 'Only sixty thousand years away. So...'

Lu-Tze, when they found him, was looking calmly up at an enormous mammoth. Under its huge hairy brow its eyes were squinting with the effort both of seeing him and of getting all three of its brain cells lined up so that it could decide whether to trample on him or gouge him out of the frost-bound landscape. One brain cell was saying 'gouge', one was going for 'trample' but the third had wandered off and was thinking about as much sex as possible.

At the far end of its trunk, Lu-Tze was saying, 'So, you've never heard of Rule One, then?'
