At twelve noon Lewis knocked on Bernard Crowther's door in the second court of Lonsdale College and found him finishing a tutorial with a young, bespectacled, long-haired undergraduate.

No rush, sir,' said Lewis. 'I can wait perfectly happily until you've finished.'

But Crowther had finished. He had met Lewis the previous Sat.u.r.day, and was anxious to hear whatever must be heard. The youth was forthwith dismissed with the formidable injunction to produce an essay for the following tutorial on 'Symbolism in Cymbeline', and Crowther shut the door. "Well, Sergeant Lewis?'

Lewis told him exactly what had occurred that morning; he made no bones about it and confessed that he had not enjoyed the subterfuge. Crowther showed little surprise and seemed anxious only about his wife.

'Now, sir,' said Lewis. 'If you say you expected a man from Kimmons to come and look at your typewriter, no harm's been done. I want to a.s.sure you of that.'

'Couldn't you have asked me?'

'Well, yes, sir, we could. But I know that Inspector Morse wanted to make as little fuss as possible.'

'Yes, I'm sure.' Crowther said it with an edge of bitterness in his voice. Lewis got up to go. 'But why? What did you expect to find?'

'We wanted to find out, sir, if we could, on what machine a certain, er, a certain communication was written.'

'And you thought I was involved?'

'We have to make inquiries, sir.'

'Well?'

'Well what, sir?'

'Did you find out what you wanted?'

Lewis looked uneasy. 'Yes, sir.'

'And?'

'Shall we say, sir, that we didn't find anything at all, er - at all incriminating. That's about the position, sir.'

'You mean that you thought I'd written something on the typewriter and now you think I didn't.'

'Er, you'd have to ask Inspector Morse about that, sir.'

'But you just said that the letter wasn't written on ...'

'I didn't say it was a letter, sir.'

'But people do write letters on typewriters don't they, Sergeant?'

'They do, sir.'

'You know, Sergeant, you're beginning to make me feel guilty.'

'I'm sorry, sir. I didn't mean to do that. But in a job like ours you've got to suspect everybody really. I've told you all I can, sir. Whatever typewriter we're looking for wasn't the one in your house.

But there's more than one typewriter in the world, isn't there, sir?'

Crowther did not contest the truth of the a.s.sertion. A large bay window gave a glorious view on to the silky gra.s.s of the second court, smooth and green as a billiard table. Before the window stood a large mahogany desk, littered with papers and letters and essays and books. And in the centre of this literary clutter there sat, four-square upon the desk, a large, ancient, battered typewriter.

On his way back to Kidlington Lewis drove through the broad tree-lined sweep of St Giles' and took the right fork to follow the Banbury Road up through North Oxford. As he pa.s.sed the large engineering block on his right, he saw a tallish woman in dark slacks and a long heavy coat walking along, every few steps sticking out a thumb in what seemed a particularly demoralized and pessimistic way. She had long blonde hair, natural by the look of it, reaching half-way down her back. Lewis thought of Sylvia Kaye. Poor kid. He pa.s.sed the blonde just as she turned her head, and he blinked hard. What a world we live in! For the lovely blonde had a lovely beard and side-whiskers down to his chin. Interesting thought...

Morse had been unable to conceal his exasperation when Lewis had reported to him earlier and when, with ridiculous rapid cert.i.tude, he had established that the letter on which he had pinned his faith had neither been written on Crowther's personal typewriter nor on any of the brands of writing paper so carefully niched from Crowther's personal store. His one worry then had been to paper over the cracks of irregularity in police procedure, and it was for this reason that he had immediately dispatched Lewis to talk to Crowther. To the report of this interview he listened with care, if without enthusiasm, when Lewis returned at 1.00 p.m.

'Not the happiest of mornings then, Sergeant.'

'No. I'd rather not do that sort of thing again, sir.'

Morse sympathized. 'I don't think we've done any harm though, have we, Lewis? I'm not worried so much about Crowther - he's hardly been above-board with us, has he? But Mrs Crowther... could have been tricky. Thanks, anyway.' He spoke with genuine feeling.

'Never mind, sir. At least we tried.' Lewis felt much better.

'What about a drink?' said Morse. The two men went off in lighter spirits.

It had occurred to neither of the policemen that women of the intelligence and experience of Mrs Margaret Crowther would do anything but automatically and unquestioningly accept the bona fides of any Tom, d.i.c.k and Harry of a tradesman. Furthermore, Mrs Crowther had herself been a confidential secretary before she married Bernard; in fact the typewriter was hers and that very morning she herself had typed out two letters on the same machine, one addressed to her husband and one addressed to Inspector Morse, c/o Thames Valley Police HQ, Kidlington. The typewriter was in perfect order, she knew that; and she had seen the nervous man from Kimmons Typewriters as he had slid open the drawers of Bernard's desk. She wondered what he was looking for, but she didn't really care. In a gaunt, weary way she had even smiled as she closed the door behind him. She would fairly soon be ready to post the two letters. But she wanted to be sure.

Morse worked at his desk through most of the afternoon. The report on Crowther's car had come in, but appeared to signify little. One long blonde hair, heavily peroxided, was found on the floor behind the nearside driving seat, but that was about it. No physical traces whatsoever of the second girl. Several other reports, but again nothing that appeared to advance the progress of the investigation. He turned his attention to other matters. He had to appear the next morning in the Magistrates' Court: there were briefs and memorandums to read. His mind was grateful to have, for a change, some tangible data to a.s.similate and he worked through the material quite oblivious to the pa.s.sage of time. When he looked at his watch at 5.00 p.m. he was surprised how swiftly the afternoon had gone by. Another day over - almost. New day tomorrow. For some reason he felt contented and he wondered to himself if that reason had anything to do with Wednesday and Sue Widdowson.

He rang Lewis, who was about to go home. Yes, of course he could come along. Perhaps he could just ring his long-suffering wife? She'd probably just got the chips in the pan. 'You say, Lewis, that Crowther has got another typewriter in his rooms in college. I think we ought to check. Well?'

'Anything you say, sir.'

'But you'd like to do it straight this time, wouldn't you?'

'I think that would be best, sir.'

'Anything you say, Lewis.'

Morse knew the Princ.i.p.al of Lonsdale College fairly well and he rang him up there and then. Lewis was a little surprised at Morse's request. The chief really was doing it properly this time. He listened to the monologue. 'How many typewriters would there be? Yes. Yes. Including those ... Yes. As many as that? But it could be done? Well that would be an enormous help, of course ... You'd rather it that way?

No, doesn't matter to me ... By the end of the week? Good. Most grateful. Now listen carefully ...'

Morse gave his instructions, iterated his thanks at inordinate length, and beamed at his sergeant when he finally cradled the phone. 'Co-operative chap that, Lewis.'

'Not much option, had he?'

'Perhaps not. But it will save us a lot of time and trouble.'

'You mean save me a lot of time and trouble.'

'Lewis, my friend, we're a team you and me, are we not?' Lewis nodded a grudging a.s.sent. 'By the end of the week we shall have evidence from every typewriter in Lonsdale College. What about that?'

'Including Crowther's?'

'Of course.'

'Wouldn't it have been a bit easier ...'

'To fire straight at the bull's-eye? It would. But you said you wanted to do this in accordance with the great unprejudiced principles of English law, did you not? We haven't got a thing on Crowther.

He's probably as innocent as my Aunt Freda.'

Since Lewis had never seen or heard of the said Aunt Freda he refrained from direct comment. 'Do you think Crowther's our man, sir?'

Morse stuck his thumb in the corner of his mouth. 'I don't know, Lewis. I just don't know.'

'I had a bit of an idea today, sir,' said Lewis after a pause. 'I saw what I thought was a girl and when I got close and she turned round she wasn't a she, she was a he.'

'You explain yourself very succinctly, Sergeant.'

'But you know what I mean.'

"Yes, I do. When we were boys we tried to look like boys; if you looked like a girl you were a cissy.

Nowadays you've got young fellows with eye make-up and handbags. Makes you wonder.'

But Morse hadn't quite seen his point and Lewis filled in the picture. He was no ideas man, he'd always realized that, and felt great diffidence in putting his notion forward. 'You see, sir, I was just thinking. We know Mrs Jarman saw the two girls' (he needn't have gone on, but Morse held his peace) 'at the bus stop. She must have been right, surely. She actually spoke to one of them and the other one was Sylvia Kaye. All right. The next thing is that the lorry driver, Baker, saw the girls being picked up at the other side of the roundabout by a man in a red car. But it was getting dark. He said they were two girls. But he might have been wrong. I could have sworn I saw a girl this morning - but I was wrong.

Everybody has been dazzled by Sylvia - all the eyes were on her and no wonder. But what if the lorry driver had seen Sylvia and another person, and what if this other person looked like a girl but wasn't.

The other person could have been a man. Remember, sir, the other girl Mrs Jarman saw was wearing slacks, and the descriptions we had from Baker fitted so well we thought they must be the same two people. But what if the other girl decided in the end not to hitch-hike to Woodstock. What if she caught up with Sylvia, told her she wasn't going to bother to go to Woodstock after all, and what if Sylvia met up with some man, probably someone she knew anyway, who'd been waiting for a lift before she got there, and the two of them hitched together. I know you've probably thought of this anyway, sir'

(Morse gave no indication either way - he hadn't) 'but I thought I ought to mention it. We've been trying to find the man who did this and I just thought he might have been in the car with Sylvia all along.'

'We've got Crowther's evidence you know, Sergeant,' said Morse slowly.

'I know, sir. I'd like to see that again if I could. As I remember it he didn't have much to say about his second pa.s.senger, did he?'

'No, that's true,' admitted Morse. 'And I can't help thinking he knows more than he's told us anyway.' He walked over to the filing cabinet, took from his files the statement of Bernard Crowther, read the first sheet, pa.s.sed it over to Lewis, and read the second. When both men had finished, they looked at each other over the table.

'Well, sir?'

Morse read it out: ' "The girl nearer to the road I saw clearly. She was an attractive girl with long fair hair, white blouse, short skirt and a coat over her arm. The other girl had walked on a few yards and had her back towards me; she seemed to be quite happy to leave the business of getting a lift to her companion. But she had darkish hair, I think, and if I remember correctly was a few inches taller than her friend ..." What do you think?'

'Not very definite is it, sir?'

Morse searched for the other relevant pa.s.sage: ' "I think the girl sitting in the back spoke only once and that was to ask the time ..." You may have got something, you know,' said Morse.

Lewis warmed to his theory 'I've often heard, sir, that when a couple are hitching the girl shows a leg, as it were, and the man keeps out of the way. You know, suddenly shows himself when the car stops and it's too late for the driver to say no.'

'That didn't happen here though, Sergeant."

'No. I know that, sir. But it fits a bit doesn't it: "seemed quite happy to leave the business of getting a lift to her companion." ' Lewis felt he should quote his evidence, too.

'Mm. But if you're right, what happened to the other girl?'

'She could have gone home, sir. Could have gone anywhere.'

'But she wanted to go to Woodstock very badly, didn't she, according to Mrs Jarman.'

'She could have got to the bus stop.'

'The conductor doesn't remember her.'

'But when we asked him we were thinking of two girls, not one.'

'Mm. Might be worth checking again.'

'And another thing, sir.' The tide was coming in inexorably and was lapping already at the sand- castles of Morse's Grand Design.

'Yes?'

'I hope you don't mind me mentioning it, sir, but Crowther says that the other girl was a few inches taller than Sylvia.' Morse groaned, but Lewis continued, remorseless as the tide. 'Now Sylvia Kaye was 5' 9", if I remember it right. If the other girl was Jennifer Coleby she must have been wearing stilts, sir. She's only about 5' 6", isn't she-'

'But don't you see, Lewis? That's the sort of thing he would lie about. He's trying to put us off. He wants to protect this other girl.'

'I'm only trying to go on the evidence we've got, sir.'

Morse nodded. He thought seriously that he should take up schoolteaching - primary school would be about his level; spelling, he thought, the safest bet. Why hadn't he thought about that height business before? But he knew why. In the Grand Design it was Crowther who had been the guilty man.

And now the waves were curling perilously close to the last of the sand-castles; had already filled the moat and breached the rampart. It was 6.00 p.m., and Lewis's second batch of chips was getting cold.

Morse limped out of the building with Lewis, and the two stood talking by the sergeant's car for several minutes. Lewis felt rather like a pupil in Morse's putative primary school who had caught his master out in the spelling of a simple word, and he hesitated to mention a little thing that had been on his mind for several days. Should he keep it for tomorrow? But he knew that Morse had a busy day in front of him at the courts. He plunged in.

'You know the letter, sir, addressed to Jennifer Coleby?'

Morse knew it by heart. What about it?'

'Could there have been some fingerprints on the original copy?'

Morse heard the question and stared blankly into the middle distance. At last he shook his head sadly. 'Too late now.'

The primary school became a distinctly firmer prospect as the minutes ticked by. The sand-castle lurched forward and prepared to topple headlong. It was time someone else took over; he would see the Commissioner.
