'Ah! I see you still don't appreciate the infinite subtlety of Bartlett's plan. What's happening outside? A fire drill! As you yourself found out, Noakes had been instructed to let the alarm ring for two minutes. Two minutes! That's a long, long time, Lewis, and during it everybody is chattering and clattering down the stairs and along the corridors. Perhaps Bartlett made quite sure that Quinn didn't shout for help; but even if he had managed to shout, I doubt if anyone would have heard him. And remember!
'We should have examined the boot, I suppose, sir.'
'But I did. There were no traces of Quinn at all. That's why I think Bartlett may have used a container of some sort.'
Then he goes out to join the rest of the staff—'
Morse nodded 'Standing meekly outside in the cold, yes. He takes over the list, which by this time has been handed round the thirty or so permanent staff, ticks in himself and Quinn as present, and finally decides that all are accounted for.'
'And it was Bartlett who rang the school in Bradford?'
'Certainly. Doubtless he'd been looking out for anything that could be used to help mislead the inevitable investigation, and he must have seen that particular letter in Quinn's tray in the registry earlier that week. If you remember, it was postmarked Monday, 17th November.'
'Then he went home and had a hearty lunch.'
'I doubt it,' said Morse. 'Bartlett's a very clever man, but basically he's not as ruthless as someone like Roope. Anyway, he's still got a lot on his mind. Certainly the trickier half of the plan is over, but he hasn't finished yet. He must have left home at about ten past one, telling his wife — perfectly correctly — that he had to call in at the office before going off to his meeting in Banbury. But before he did that—'
'He called in at Studio 2.'
