Bernard started, and his heart blessed all the G.o.ds that were and are and are to be. "Where the h.e.l.l have you been?' In a fraction of a second his terrible, agonized fear had flashed to anger - relieved, fierce, beautiful anger.

'As a matter of fact the starter-motor's gone on the Mini. I couldn't get anyone to fix it and in the end I had to catch a bus.'

'You could have let me know.'

'Oh yes, of course. You want me to ring round all the garages, then you, and then presumably the kids.' Margaret herself was becoming very angry. "What's all the fuss about? Just because I'm late for a change!'

'The children have been waiting no end of a time.'

'So what!' Margaret stormed into the house, and Bernard heard the high-pitched voices within. He closed the front gate and then the garage. He locked and bolted the front door. He felt happy, happier than he had felt for many days and many hours.

12 Wednesday, Thursday; 6,7 October

Morse did not know what had persuaded him, after seven months of promises and prevarications, to fill in the ragged gaping hole above the kitchen door where the electrician had led in the wires for a new power-point. Everything had been wrong from the start anyway. The Polyfilla powder, purchased some two years previously, had hardened into a solid block of semi-concrete within its packet; the spatula he used for cracking eggs and filling cracks had mysteriously vanished from the face of the earth; and the primitive household steps never had stood four-square on their rickety legs. Perhaps he had taken inspiration from Mr Edward de Bono and his recipe for lateral thought. But whatever the motive for his sudden urge to see the wretched hole filled in, Morse had taken a vertical plunge, like some free-fall parachutist, from the top of the steps, when the cord restraining the uprights to a functional 30 angle suddenly snapped and the whole apparatus collapsed into a straight line beneath him. Like Hephaestus, thrown o'er the crystal battlements, he landed with an agonizing jolt upon his right foot, lay with a feeling of nausea for two or three minutes, wiping the cold sweat which formed upon his brow, and finally limped his way to the front room and lay breathing heavily on the settee. After a while the foot was a little easier and he felt somewhat rea.s.sured; but half an hour later the swelling began and a fitful, sharp pain nagged away at his instep. He wondered if he could drive, but knew it would be foolish to try. It was 8.30 p.m. on Tuesday, 5 October. Only one thing for it. He hobbled and hopped across to the telephone and rang Lewis, and within the half hour he was sitting disconsolately in the accident room of the Radcliffe Infirmary, waiting for the result of the X-ray. A young boy sitting on the bench next to Morse was wringing his left hand in some agony (car door) and two men badly injured in a road accident were wheeled by for priority treatment. He felt a little less depressed.

He was finally seen by an almost unintelligible Chinese doctor who held up his X-ray pictures to the light with the disinterestedness of a bored guest having a casual glance at one of the holiday slides of his host. 'n.o.brocken. Creepancrushes.' From the competent nurse into whose hands he was now de- livered, Morse gathered that no bones were broken and that the treatment prescribed was crepe bandage and hospital crutches.

He expressed his thanks to nurse and doctor as he swung along diffidently towards the waiting Lewis. 'You,' shouted the doctor after him. "You, Mr Morse. Nowork twodays. You rest. OK?'

'I think I shall be all right, thanks,' said Morse.

'You, Mr Morse. Youw.a.n.gebetter, eh? Nowork. Two days. Rest. OK?'

'OK.'Oh G.o.d!

Morse hardly slept through Tuesday night; he had a vicious toothache in each of the toes on his foot. He swallowed Disprin after Disprin and finally towards dawn dozed off from sheer exhaustion.

Lewis called several times during the prolonged agonies of Wednesday and watched the Inspector fall into a blessedly deep sleep at about 9.00 p.m.

When Lewis greeted him the next morning, Morse felt better; and because he felt better, his mind reverted to the murder of Sylvia Kaye, and because his mind was not now wholly preoccupied with the tribulations of his right foot, he felt a great depression grow upon him. He felt like a quiz contestant who had almost got some of the answers right, had others on the tip of his tongue, but had finished up with nothing. One always longed to start again ...

He lay with these troubled thoughts on his mind. Lewis was fussing around. Good old Lewis.

They'd all be having a good laugh at the station, he thought. Humiliating, falling off a ladder. Well he hadn't fallen off a ladder. He'd fallen through one.

'Lewis! You told everybody what happened, I suppose?'

'Yes, sir.'

'Well?'

'They think you're making it up. They think you've got gout really. You know - too much port.'

Morse groaned. He could picture himself limping round with every other person stopping him to enquire into the circ.u.mstances of the disaster. He'd write it all out, have it photocopied, and distribute the literature around the station.

'Still painful, sir?'

'Of course it b.l.o.o.d.y well is. You've got millions of nerve endings all over your b.l.o.o.d.y toes. You know that, don't you?"

'I had an uncle, sir, who had a beer barrel run over his toes.'

'Shut up,' winced Morse. The thought of anything, let alone a beer barrel, being within three feet of his injured foot was quite unbearable. Beer barrel, though. Morse was getting better.

'Are the pubs open yet?'

'Fancy a drink, sir?' Lewis looked pleased with himself.

'Wouldn't mind a jar.'

'As a matter of fact I brought a few cans in last night, sir.'

'Well?'

Lewis found some gla.s.ses, and positioning a chair a goodly distance from 'the foot', poured out the beer.

'Nothing new?' asked Morse.

'Not yet.'

'Mm.'

The two men drank in silence. Some of the answers almost right ... others on the tip of his tongue ...

What, wondered Morse, if he had been right, or almost right? If only he could start again ... Suddenly he sat up, forgot his incapacity, yelped 'Oh, me foot!' and leaned back again into his nest of pillows.

He could start again, couldn't he? 'Lewis. I want you to do me one or two favours. Get me some writing paper - it's in the writing-desk downstairs; and what about some fish and chips for lunch?'

Lewis nodded. As he went off for the writing paper Morse interrupted him.

'Three favours. Open a few of those cans.'

A thought had been floating around in Morse's mind for several days, elusive as a bar of soap in a slippery bath. In the beginning was the thought, and the thought became word and Morse unwrapped the text carefully and read the message. Im Anfang war die Hypothese. In the beginning was the hypothesis. But before formulating any hypothesis, even of the most modest order, Morse decided that he would feel sharper in body, mind and spirit with a good wash and a shave. Slowly and painfully he got out of bed, tacked crabwise around the walls and ended up by hopping over the last few feet of the bathroom floor. It took him almost an hour to complete his toilet, but he felt a new man. He retraced his irregular progress and gently heaved his right foot into a comfortable niche alongside a spare pillow stuffed down at the bottom of the bed. He felt exhausted but wonderfully refreshed. He closed his eyes and fell fast asleep.

Lewis wondered if he should wake him, but the pungent smell of fried batter and vinegar saved him the trouble.

'What's the time, Lewis? I've been asleep.'

'Quarter past one, sir. Do you want the fish and chips on a plate? Me and the wife always eat 'em off the paper - seems to taste better somehow.'

'They say it's the newsprint sticking to the chips,' replied Morse, taking the oily package from his sergeant and tucking in with relish. 'You know, Lewis, perhaps we've been going about this case in the wrong way.'

'We have, sir?'

'We've been trying to solve the case in order to find the murderer, right?'

'I suppose that's the general idea, isn't it?'

'Ah, but we might get better results the other way round.'

'You mean...' But though Morse waited it was clear that Lewis had no idea whatsoever what he meant.

'I mean we ought to find the murderer in order to solve the case.'

'I see,' said Lewis, unseeing. - 'I'm glad you do,' said Morse. 'It's as clear as daylight - and open some of these b.l.o.o.d.y curtains, will you?'

Lewis complied.

'If,' continued Morse, 'if I told you who the murderer was and where he lived, you could go along and you could arrest him, couldn't you?' Lewis nodded vaguely and wondered if his superior officer had caught his skull on the kitchen sink before landing on his precious right foot. "You could, couldn't you? You could bring him here to see me, you could keep him at a safe distance from my grievous injury - and he could tell us all about it, eh? He could do all our work for us, couldn't he?'

Morse jabbered on, his mouth stuffed with fish and chips, and with genuine concern Lewis began to doubt the Inspector's sanity. Shock was a funny thing; he'd seen it many times in road accidents.

Sometimes two or three days afterwards some of the parties would go completely gaga. They'd recover of course ... Or had Morse been drinking? Not the beer. The opened cans were still unpoured. A heavy responsibility suddenly seemed to descend on Lewis's shoulders. He was sweating slightly. The room was hot, the autumn sun bright upon the gla.s.s of the bedroom window.

'Can I get you anything, sir?'

"Yep. Flannel and soap and towel. By Jove, your wife's right, Lewis. I'll never eat "em off a plate again.' A quarter of an hour later a bewildered sergeant let himself out of the front door of Morse's flat.

He felt a little worried and would have felt even more so if he had been back in the bedroom at that moment to hear Morse talking to himself, and nodding occasionally whenever he particularly approved of what he heard coming from his own lips.

'Now my first hypothesis, ladies and gentlemen, and as I see things the most vital hypothesis of all - I shall make many, oh yes, I shall make many - is this: that the murderer is living in North Oxford. You will say this is a bold hypothesis, and so it is. Why should the murderer not live in Didcot or Sidcup or even Southampton? Why should he live in North Oxford? Why not, coming nearer home, why not just in Oxford? I can only repeat to you that I am formulating a hypothesis, that is, a supposition, a proposition, however wild, a.s.sumed for the sake of argument; a theory to be proved (or disproved - yes, we must concede that) by reference to facts, and it is with facts and not with airy-fairy fancies that I shall endeavour to bolster my hypothesis. Itn Anfang war die Hypothese, as Goethe might have put it.

And please let it not be forgotten that I am Morse of the Detective, as d.i.c.kens would have said. Oh yes, a detective. A detective has a sensibility towards crime - he feels it; he must feel it before he can detect it. There are indications which point to North Oxford. We need not review them all here, but the ambience is right in North Oxford. And if I am wrong, why, no harm is done to our investigation. We are propounding a hypothesis, that is, a supposition, a proposition, however wild ... I've said all that before, though. Where was I, now? Oh yes. I wish you to accept, provisionally, dubiously, hopelessly if needs be, my premier hypothesis. The murderer is a resident of North Oxford. Now I mentioned facts, and I shall not disappoint you. Aristotle cla.s.sified the animals, I believe, by subdividing them, and sub- division will be our method of procedure. Aristotle, that great man, divided and subdivided - species, subspecies, genera (Morse was getting lost) genera, species, subspecies and so on until he reached - what did he reach? - the individual specimen of the species.' (That sounded better.) 'I, too, will divide.

In North Oxford there are, let us say, "x" number of people. Now we further hypothesize that our murderer is a male. Why can we be confident of this fact? Because, ladies and gentlemen, the murdered girl was raped. This is a fact, and we shall bring forward at the trial the evidence of eminent medical personnel to...' Morse was tiring a little, and fortified himself with another can of beer. 'As I was saying, our murderer is male. We can therefore divide our number x by, let us say, er, four -leaving the women and children out of our reckoning. Now can we subdivide again, you will ask? Indeed, we can.

Let us guess at the age of our murderer. I put him - I am diffident, and you will accuse me of formulating sub-hypotheses - between 35 and 50. Yes, there are reasons ...' But Morse decided to skip them. They weren't all that convincing, perhaps, but he had reasons, and he wished to sustain the impetus of his hypothesis. 'We may then further subdivide our number x by two. That seems most reasonable, does it not? Let us continue. What else can we reasonably hypothesize? I believe - for reasons which I realize may not be fully acceptable to you all - that our suspect is a married man.'

Morse was feeling his way with an increasing lack of confidence. But the road ahead was already clearing; the fog was lifting and dissipating in the sun, and he resumed with his earlier briskness. 'Now this means yet a further diminution in the power of x. Our x is becoming a manageable unit, is it not?

But not yet is the focus of our camera hypothetica fixed with any clear delineation upon our unsuspecting quarry. But wait! Our man is a regular drinker, is he not? It is surely one of our more reasonable claims, and gives to our procedure not only the merits of hypothetical plausibility, but also of extreme probability. Our case is centred upon the Black Prince, and one does not visit the Black Prince in order to consult the tax inspector.' Morse was wilting again. His foot was throbbing again with rhythmic pain, and his mind wandered off for a few minutes. Must be those Disprin. He closed his eyes and continued his forensic monologue within his brain.

He must, too, surely he must, figure in at least the top 5 % of the IQ range? Jennifer wouldn't fall for an ignorant buffoon, would she? That letter. Clever chap, well schooled. If he wrote it. If, if, if. Carry on. Where's our x now? Go on. He must be attractive to women. Yet who can say what attracts those lovely creatures? But yes. Say yes. Subdivide. Cars! G.o.d, he'd forgotten cars. Not everyone has a car.

About what proportion? Never mind, subdivide. Just a minute - red car. He felt slightly delirious. Just a fraction longer ... That really would be a significant subdivision. The x was floating slowly away, and now was gone. The pain was less vicious. Comfortable ... almost ... comfortable ...

He was woken at 4.00 p.m. by Lewis's inability to manage the front door without a disturbing clatter.

And when Lewis anxiously put his head round the bedroom door, he saw Morse scribbling as furiously as Coleridge must have scribbled when he woke up to find, full grown within his mind, the whole of Kubla Khan.

'Sit down, Lewis. Glad to see you.' He continued to write with furious rapidity for two or three minutes. Finally he looked up. 'Lewis, I'm going to ask you some questions. Think carefully -don't rush! - and give me some intelligent answers. You'll have to guess, I know, but do your best.'

Oh h.e.l.l, thought Lewis.

'How many people live in North Oxford?'

'What do you call "North Oxford", sir?'

'I'm asking the questions, you're answering 'em. Just think generally what you think North Oxford is; let's say Summer-town and above. Now come on!'

'I could find out, sir.'

'Have a b.l.o.o.d.y guess, man, can't you?"

Lewis felt uncomfortable. At least he could see that only three of the beer cans were empty. He decided to plunge in. 'Ten thousand.' He said it with the a.s.surance and unequivocal finality of a man asked to find the sum of two and two.

Morse took another sheet of paper and wrote down the number 10,000. 'What proportion of them are men?'

Lewis leaned back and eyed the ceiling with the confidence of a statistical consultant. 'About a quarter.'

Morse wrote down his second entry neatly and carefully beneath the first: 2,500. 'How many of those men are between 35 and 50?'

Quite a lot of retired people in North Oxford, thought Lewis, and quite a lot of young men on the estates. 'About half, no more.

The third figure was entered: 1,250. 'How many of them are married, would you say?'

Lewis considered. Most of them, surely? 'Four out of five, sir.'

Morse formed the figures of his latest calculation with great precision: 1,000.

'How many of them regularly go out for a drink - you know what I mean - pubs, clubs, that sort of thing?'

Lewis thought of his own street. Not so many as some people thought. The neighbours on either side of him didn't - mean lot! He thought of the street as a whole. Tricky this one. 'About half.'

Morse revised his figure and went on to his next question.

'You remember the letter we had, Lewis. The letter Jennifer Coleby said she knew nothing about?'

Lewis nodded. 'If we were right in thinking what we did, or what I did, would you say we were dealing with a man of high intelligence?' 'That's a big if, isn't it, sir?'

'Look, Lewis. That letter was written by our man - just get that into your head. It was the big mistake he made. It's the best clue we've got. What the h.e.l.l do they pay us for. We've got to follow the clues, haven't we?' Morse didn't sound very convinced, but Lewis a.s.sured him that they had to follow the clues.

'Well?'

'Well what, sir?'

'Was he an intelligent man?'

'Very much so, I should think.'

'Would you think of writing a letter like that?' , 'Me? No, sir.'
