“So it all turned out to be this Mervyn fellow’s fault,” remarked Alistair, having listened in, eyes closed, on the summary of last night’s revelations. “But I don’t see why you girls are so shocked about it. I thought everything was always the man’s fault?” He yawned, stretching his long bulk even more luxuriously against the sofa cushions, and continued: “Isn’t anyone going to pour me another cup of coffee?”

It was Diana, of course, who reached for the coffee pot, and Bridget watched the eagerly subservient movement with her usual flicker of irritation. Why couldn’t the wretched man ever do anything for himself? The irritation, however, was a small thing – and she recognised it as such – compared with the enormous relief she was still feeling at finding life in the flat going on exactly as usual this Saturday morning. After Diana’s panicky telephone call last night, and her own somewhat dilatory response to it, she had travelled back this morning in an uncomfortable state of guilt and unease. Suppose something awful really had happened at the flat in her absence? Suppose she’d arrived back to find her flatmate dead, or abducted, or in hospital, because of something that would never have happened if Bridget had rushed back as soon as she was summoned? She’d even felt relieved, as she walked up the road from the bus stop, to see that Acorn House was still standing.

She was even more relieved, as she mounted the second flight of stairs, to hear the sound of voices pitched at an ordinary conversational level, with no indication of trauma or crisis. She was actually glad to hear Alistair’s annoying tones, mocking something someone had just said. Normally she would have been distinctly put out to discover Alistair already here before midday on a Saturday, as it would almost certainly mean that they would have him for the whole weekend. This time, though, after all her fears and imaginings, his familiar provoking presence was positively reassuring. So much so that she even found herself smiling when he stretched out his arms towards her in idle greeting and lamented the fact that he was too lazy to get off the sofa to come and kiss her.

“If a man be a fool” she quoted, “Pray God that he may also be lazy, for it will keep him out of many troubles,” and soon she had joined them in what had obviously been something of a marathon coffee-break.

By now, Norah’s former reticence was quite gone. She seemed only too glad to tell and re-tell her unhappy story. After all the long months of secrecy, of trying to hide her tragic family situation from friends and neighbours, of enduring the social isolation which inevitably goes with hiding one’s real situation from absolutely everybody, she found it an indescribable relief to be confiding at last in listeners who were not only interested but, far more important, had never known her as the person she once was. Among strangers, there was hardly any pain involved in playing the role of victim, because they have never known any other way; to become a victim, a “Poor Thing”, under the shocked gaze of old friends who had previously known you as an amusing, life-enhancing, top-of-the-world sort of person, was humiliating beyond all endurance.

So, having already told her story in such detail to Diana, Norah was now quite ready to repeat the salient points for Bridget’s benefit.

“So you see, Bridget,” she explained, “The reason I’ve run away like this isn’t just that I can’t stand it, though of course I can’t. What I think I’m really trying to do is to force Mervyn to realise that Christopher is mentally ill, so that he will be forced to do something about it. Get him treated somehow – get him into hospital – something. I know that that’s what he needs, and if Mervyn is left to cope with him single-handed for even a few days, then he’ll find it out for himself. You see, all the time I’m there he can get away with turning a blind eye to the awful things Christopher does, because I’m the one coping with the results. You see, the point is, Mervyn finds it intolerably humiliating to face the fact that he, a top-ranking psychiatrist, has a mentally-ill son. But if I’m not there, he’ll have to face it. When he comes home and finds that Christopher has wrecked something for some weird reason inside his head – and when he can’t blame it on me, whatever it is, because I’m not there – then he’ll have to face it, won’t he? He’ll have to do something about it.”

“Such as what?” put in Alistair drily. “Haven’t you heard of Community Care? Don’t you know what it means? It means you. On the job 24 hours a day, seven days a week, without any pay at all – what could be cheaper? And in the case of your son – you won’t even get anyone doing an assessment or prescribing the appropriate pills for him to refuse to take. Since the patient’s father is some kind of a shrink, they’ll assume that he’s seeing to all that kind of thing, because he’s the expert.”

Here he sighed, and raised his eyes to the ceiling in mock despair.

“Nobody seems to understand what an expert is, and what can be expected of him. As an expert myself, in a small way, I can tell you. An expert is the man who can’t be expected to do anything. He’s there simply to criticise the people who do do things.”

“But, Alistair, he’ll have to do something! You don’t understand!” Diana interrupted. “The kind of things this boy gets up to when he’s in one of his bad spells – tell him, Norah. Tell him some of the things you’ve told me.”

And Norah, willingly enough by now, did so.

“I’d let him go out shopping,” she began. “I did that sometimes, when he seemed to be having a good day, and mostly he was very efficient. I was upstairs when he arrived back, and when I came down I found he’d brought home this load of groceries from the supermarket and had put it all in the washing-machine. With detergent, and switched on to “Hot”. If I hadn’t been there to cope with the worst of the mess before Mervyn got home – if he’d come in and found the butter and the Rainbow Dip and the soused herrings and bananas all whirling round, and no one but himself to do something about it … Mind you, he got involved in the end, because we had to get a man in to fix the washing machine. The works were all bunged up with gunge even after I’d cleaned it … Mervyn blamed me, of course. He said I didn’t understand that someone as brilliant as Christopher was bound to be a bit absent-minded at times.

“But it wasn’t absence of mind, I knew it wasn’t, it was full-blown delusion. Christopher explained it to me in his weird, logical-sounding way. He was afraid of food-poisoning, he said, from the modern methods of chilling and storing, and so he’d decided that all super-market food should be given a thorough wash before being eaten.

“But Mervyn still managed to blame me. And that’s why I think that without me there – with no one to blame but Christopher himself … Without me there, he’ll have to …”

“Hasn’t it occurred to you that he might walk out too? Just like you did? If I came home and found the washing machine churning up the muesli and the gorgonzola and the smoked salmon and the Mothers’ Pride, I’d be through the front door before you could even turn it to ‘Wool and Fine Fabrics’ …”

At Alistair’s throwaway contribution to the problem, Norah gave a little gasp of dismay.

“Oh no! Oh, surely he wouldn’t! Oh, I never thought of that! When I rang Christopher last night, he never mentioned his father at all. I wonder if that might mean … Oh, my God! If he’s been actually alone all this time …!”

She was actually biting her nails now, her restless brown eyes darting from one face to another; her whole body was tense and somehow shrunken, like a cornered mouse.

“Oh, he wouldn’t!” she said again, in tones which made it perfectly clear that he would. Or might. Or already had. Who knew what a man would do when brought face to face with the unendurable?

“Oh, what shall I do? Oh, I should never have …! Oh, I must go back! I must see what’s going on … I don’t know what he might get up to, all on his own like that! And the neighbours …!”

It was impossible not to notice the eager, almost hungry look on Diana’s face while this exchange was going on, and Bridget realised that the possibility of interviewing Norah for the forthcoming Community Care programme was taking shape in her friend’s mind, in spite of her earlier protestations about it being unethical to interview friends.

Why should it be? What was wrong with it – if Norah was willing? Bridget recalled Diana’s disappointment on learning that Norah was a dead loss for the Battered Wives programme – but was there not a future programme already in the pipe-line on the subject of Community Care? And Norah’s predicament was not merely that of the run-of-the-mill carer of any mental patient. Hers displayed a new and intriguing angle: the problem of the carer whose partner refuses to recognise that there is a problem at all. Partnership difficulties were bound to be quite a feature of the new series, Bridget reflected. Diana had already mentioned cases in which marriages had broken up because one partner – usually the husband – simply could not stand the stress and the social stigma. But in Norah’s situation there was this new and piquant twist of the husband refusing to recognise the truth. Norah had already shown herself willing to reveal all to three near-strangers; might she not be equally willing – even eager – to reveal her problems to millions of viewers? It was amazing how many people were willing to do just this. Why shouldn’t Norah be one of them?

It would have to be done anonymously, of course. Bridget tried to visualise Norah in silhouette, with her back to the camera, and her voice scrambled into near-inaudibility.

Even so, Diana would have to go carefully, Bridget reflected. Her approach would have to be tentative, and very reassuring.

“I tell you what, Norah,” Diana was saying, as if as a footnote to Bridget’s speculations, “Why don’t I drive you down there this afternoon? I can see you’re anxious about how your son is managing; of course you are; but if you are planning to go and see for yourself, I think you ought to have someone with you. Someone to spy out the land, as it were. I mean, your husband may easily still be there, he might answer the door to you, and I gather that would be a bit of a disaster. So what I’m thinking of is this. If we went together, I could leave you in the car while I went ahead to your house and sussed it out. I could find out who’s in and who isn’t in, and roughly what’s going on. If it’s a boy who answers the door, and he seems to be alone in the house, then I’ll signal to you to come along. If it’s a middle-aged man, I’ll think up some plausible pretext: Market Research, or canvassing for the Labour Party, or something.”

“Jehovah’s Witnesses would be best,” contributed Alistair. “You’ll look perfect for the part, sweetie, with that moist and soulful look you always have in your eyes when you are on the trail of your next T.V. victim. We’ll borrow a Bible from the local vicar and confront Norah’s hubby with a suitable text – ‘He that diggeth a pit shall fall into it’ – something like that. You’ll be an absolute wow, darling, I can just see you! When you tell him that the end of the world is nigh, he’ll positively shake in his polished Consultant shoes. The only thing is, darling, I thought your ricketty little clapped-out banger was having its MOT test this afternoon. Doesn’t that throw a spanner in the do-goodery? For today, anyway?”

“Yes … Well …” Diana hesitated. “They said it would be ready by three, and so I thought …”

“You thought it would be ready by three, is that what you’re trying to tell me? You really make me wonder whose head it is that wants examining. There’s no chance at all that you’ll get to this God-forsaken place before night. Somewhere in Hertfordshire, didn’t you say? Look, why don’t I take you both? And Bridget too. I’ll take you all out to lunch, if you think you can afford it. I’ve at least mastered the Women’s Lib principles about lunching with a chauvinist pig, and I heartily approve of them. Especially when it’s three of you.”

And lurching from the sofa with surprising agility, he donned his anorak, located his car keys, and stood waiting, apparently taking for granted the acquiescence of all concerned.
