'Nearly a year.'
'Didn't you think it a bit dangerous — telling someone else?'
'I suppose it was. But it meant we could have a room once a week.'
'Palmer told you this morning that I knew?'
'Yes.' She had answered mildly enough thus far. But the old flash blazed in her eyes once more. 'How did you know?'
'I had to guess. But there had to be some reason. It was accidental, really. I checked the night-school register for Wednesday, 29 September, to see whether Mrs. Crowther had been present. She wasn't. But I noticed another name on the list, and she
'You've got a suspicious mind, Inspector.'
'And when did this business of the letters start?'
'In the summer. Stupid really. But it worked all right — so they said.'
'Can you give me your solemn word, Miss Coleby, that you will say nothing of this to anyone?'
'Yes, Inspector. I think I owe you that at least.'
Morse got up. 'Well, get someone to take her back to work, Lewis. We've taken up enough of Miss Coleby's time.' A flabbergasted Lewis gaped at them like a fish out of water, and Jennifer looked round and gave him a wan, sad smile.
'You're not being very fair to me are you, sir?' Lewis seemed downcast and annoyed.
'What do you mean?' asked Morse.
'You said the case was nearly over.'
'It is over,' said Morse.
'You know who murdered her?'
'A person has already been arrested and charged with the murder of Sylvia Kaye.'
'When was this?'
'This morning. Here!' Morse took out the letter which Lewis himself had brought from Jennifer Coleby, and passed it over. Lewis took out the sheet of paper and read with blind, blank, uncomprehending disbelief the one line answer that Miss Coleby had written to Morse's question.
'Yes,' said Morse softly. 'It's true.'
Lewis was full of questions, but he received no answers. 'Look, Lewis, I want to be alone. You go home and look after your wife for a change. I'll talk to you on Monday.'
The two men left the office. Lewis got his coat and was soon away. But Morse walked slowly to the cells at the far end of the north wing.
'Want to go in, sir?' said the sergeant on duty.
Morse nodded. 'Leave us alone, will you?'
'Anything you say, sir. Cell number 1.'
Morse took the keys, unbolted the main door to the cells and walked along to cell number 1. He put his hands on the bars and stood staring sadly through.
'Hello, Sue,' he said.
CHAPTER THIRTY-ONE
Monday, 25 October
THE DAY HAD BROKEN bright and clear, but by mid-morning a melancholy army of heavy grey cloud had massed overhead; and flurries of light rain were already sprinkling the window panes of Morse's office as, for the last time on the case of Sylvia Kaye, the two detectives faced each other across the desk.
'What did we know about Miss X?' asked Morse, and proceeded to answer the question himself. 'We knew roughly what she looked like, we knew roughly what she was wearing, and we knew roughly what age she was. It was a start, but it could never have got us very far. But we also knew that the two girls waiting at the bus stop not only knew each other but that
